        break options.
        * src/hal_if.c: Make declaration of the hal_saved_interrupt_state
        variable conditional on an implementation of the new CDL interface.

2010-11-20  John Dallaway  <john@dallaway.org.uk>

        * cdl/hal.cdl: Suppress -fprofile-arcs (which implies -lgcov) when
        generating extras.o.

2010-10-09  John Dallaway  <john@dallaway.org.uk>

        * include/hal_if.h (CYGNUM_CALL_IF_available_x): fix typo in
        previous patch.

2008-11-20  Bart Veer  <bartv@ecoscentric.com>

        * cdl/hal.cdl, include/hal_if.h, src/hal_if.c: expunge
        CYGSEM_HAL_VIRTUAL_VECTOR_CLAIM_CACHE and the corresponding code.

2008-05-20  Jonathan Larmour  <jifl@eCosCentric.com>

        * src/thread-packets.c (threadmatch): Silence pointer signedness

        Instead of using a local variable to avoid compiler reordering
        when taking the address of a label, instead call an external function.
        (NB making the variable volatile isn't sufficient).

2008-05-13  Chris Zimman  <czimman@bloomberg.com>

        * cdl/hal.cdl: Work around problem with current ARM EABI tools by
        using /dev/null as linker script. Should be safe with other tools.

2007-11-27  Bart Veer  <bartv@ecoscentric.com>

        * src/hal_if.c (delay_us): use HAL_DELAY_US() rather than the

2007-09-27  Grant Edwards <grante@visi.com>

        * include/hal_endian.h (SWAP16): Fix "return value" so

        CYGBLD_ATTRIB_USED so that gcc 3.4.4 does not discard entries
        which are not refereced explicitly. Problem reported by
        Oliver Munz.
        
2005-06-26  Bart Veer  <bartv@ecoscentric.com>

        * doc/hal.sgml: make HAL_DELAY_US() mandatory and define it to be
        thread-safe.

        * include/hal_if.h: Make monitor locking work with CYGPKG_LWIP.

2004-05-19  John Newlin <jnewlin@stretchinc.com>

        * src/hal_stub.c:
        (cyg_hal_gdb_interrupt) 
        (cyg_hal_gdb_remove_break): Changed both to use
        _read_mem_safe/__write_mem_safe for inserting a breakpoint, and
        restoring the original instruction.
        The Xtensa architecture (and others maybe?) can have unaligned
        instructions, which caused unaligned load/store exception.
        
2004-04-22  Jani Monoses <jani@iv.ro>

         * cdl/hal.cdl :
         Invoke tail with stricter syntax that works in latest coreutils. 

2004-02-23  Jonathan Larmour  <jifl@eCosCentric.com>

        * cdl/debugging.cdl (CYGDBG_HAL_DEBUG_GDB_INCLUDE_STUBS): Included
        stubs should always mean saving full context both on interrupts
        and context swaps, so make it explicit.

2004-01-05  Gary Thomas  <gary@mlbassoc.com>

        * include/hal_if.h: Minor fixup - new 'fconfig' functions broke 
        existing uses of CYGACC_CALL_IF_FLASH_CFG_OP.  Added a new macro
        CYGACC_CALL_IF_FLASH_CFG_OP2 which handles new API and a wrapper
        to handle the old way (backwards compatability).

2003-12-21  Gary Thomas  <gary@mlbassoc.com>

        * src/hal_if.c (flash_config_op): 
        * include/hal_if.h: New expanded functions for RedBoot 'fconfig'
        database.

2003-09-04  Patrick Doyle  <wpd@dtccom.com>

        * include/hal_if.h: 
        * src/hal_if.c (flash_fis_op): Added support for the rest of the
        FIS operations.

2003-08-06  Bob Koninckx <bob.koninckx@mech.kuleuven.ac.be>

        * src/drv_api.c: Added definition of cyg_interrupt_post_dsr() for
        use in those HALs that need it.

        * include/hal_arbiter.h (hal_call_isr): Removed ifdef on
        CYGFUN_HAL_COMMON_KERNEL_SUPPORT around test and call to
        cyg_interrupt_post_dsr().

2003-07-21  Nick Garnett  <nickg@balti.calivar.com>

        * doc/hal.sgml: Reorganized description of clock and timer related
        stuff into their own section and added a piece about how to change
        the clock frequency.

2003-06-25  Nick Garnett  <nickg@balti.calivar.com>

        * src/hal_if.c (delay_us): The first test against
        CYGNUM_KERNEL_COUNTERS_RTC_PERIOD is now against the period
        divided by two. By the time we get to this test we know that usecs
        can never be > usec_per_period/2 so we can double the range of
        period values that we can handle without overflow and use the more
        efficient approximation. The second test is not changed since we
        cannot make the same assumptions about the elapsed count.

2003-06-24  Jonathan Larmour  <jifl@eCosCentric.com>

        * src/generic-stub.c (crc32): Fix crctable option name typo.

        * src/hal_if.c (hal_if_init): Remove kill_by_reset.
        (kill_by_reset): Remove, unused.
        (reset): ifdef test on HAL_PLATFORM_RESET and assert on reset failure.

        * cdl/interrupts.cdl (CYGNUM_HAL_COMMON_INTERRUPTS_STACK_SIZE): No
        reason to forbid people setting this quite small.
        
2003-06-19  Nick Garnett  <nickg@balti.calivar.com>

        * src/hal_if.c (delay_us): Reorganized to cope with high frequency
        timers by eliminating a source of arithmetic overflow. 

2003-05-06  Mark Salter  <msalter@redhat.com>

        * src/hal_stub.c (handle_exception_exit): Call sys_profile_reset from
        here. Setup to return through return_from_stub() when appropriate.
        (return_from_stub): New function to call CYGACC_CALL_IF_MONITOR_RETURN
        from thread context.

        * src/generic-stub.c (__handle_exception): Call exit_vec if
        hal_syscall_handler returns negative number.

2003-04-08  Mark Salter  <msalter@redhat.com>

        * src/hal_misc.c (hal_default_isr): Allow HAL to override default
        GDB vector matching test.

2003-04-02  Gary Thomas  <gary@mlbassoc.com>

        * src/generic-stub.c: 
        * include/generic-stub.h: Cleanup when program args are not
        supported (remove some unused static storage).

2003-03-03  Knud Woehler <knud.woehler@microplex.de>

        * src/hal_if.c:
        * include/hal_if.h: Add CYGNUM_CALL_IF_FLASH_FIS_OP. FIS read
        via the virtual vector table.
        
2003-02-24  Jonathan Larmour  <jifl@eCosCentric.com>

        * cdl/hal.cdl: Fix doc links.

        * doc/hal.sgml: hal-common-current-doc-porting-sgml entity ->

        * include/generic-stub.h: Add defines for Z packet types.
        * src/bplist-dynamic.c: Add support for deferred hardware breakpoint
        and watchpoint insertion/deletion. This gets around gdb problem where

        retcode/errno/ctrlc status every F packet.

2002-04-23  Jesper Skov  <jskov@redhat.com>

        * doc/porting.sgml: Fix some typos.

2002-04-22  Jonathan Larmour  <jlarmour@redhat.com>

        * include/generic-stub.h: Prototype __getpacket().
        * src/generic-stub.c: Rename getpacket() -> __getpacket(),
        remcomInBuffer -> __remcomInBuffer, and

        * doc/porting.sgml: Platform HAL porting guide tidied up and
        expanded somewhat. Some work also done on variant

        tags to make any future restructuring easier.

2002-03-14  Nick Garnett  <nickg@redhat.com>

        check macros.

2002-03-06  Nick Garnett  <nickg@redhat.com>

        * tests/cache.c: Changed tests so that zero sized caches and HALs

        if buffer is empty.

2002-02-20  Nick Garnett  <nickg@redhat.com>

        * doc/hal.sgml: Updated and tidied. Now includes porting guide
        from a separate file.

        * doc/porting.sgml: Added this file to contain the porting guide
        section of the HAL document. This is currently largely a
        conversion of Jesper's porting guide from the website.
        Unfortunately I have had no time to do much more than include it
        wholesale, with only minor edits. There are some notes at the end
        of the file describing what I would like to do.

2002-02-18  Nick Garnett  <nickg@redhat.com>

        * doc/hal.sgml: Restructured most of this document and rewrote
        large chunks of the basic HAL description stuff. Only the skeleton
        of the porting guided is currently done. This checkin in mostly
        for safety and to let others read the current state.

        * include/hal_if.h (CYGNUM_FLASH_CFG_OP_CONFIG_INT): New defines for
        getting Flash Config options out of RedBoot using VV call
        CYGACC_CALL_IF_FLASH_CFG_OP().  These need to be kept uptodate
        with (or must override) those in RedBoot's flash_config.h
        Previously only used for getting an ESA.

2002-01-25  Hugo Tyson  <hmt@redhat.com>

        * src/generic-stub.c (__process_packet): If detach or kill, call
        sys_profile_reset() if BSP_SYSCALLS_GPROF are enabled, to clear
        out any dangerous state there.  Such as a callback function
        pointer into application code.

2002-01-23  Jonathan Larmour  <jlarmour@redhat.com>

        * include/drv_api.h: Add cyg_drv_interrupt_mask/unmask_intunsafe
        * src/drv_api.c: Ditto. And modify 
         cyg_drv_interrupt_mask/unmask to be interrupt safe.
        
2002-01-21  Mark Salter  <msalter@redhat.com>

        * include/hal_spd.h: New file. Definitions for SDRAM module SPD.

        twice.

2001-12-12  Jesper Skov  <jskov@redhat.com>

        * include/hal_stub.h: Add goto to the used label.
        * src/hal_misc.c: Added (dummy) got for label used in
        CYGARC_HAL_GET_RETURN_ADDRESS_BACKUP.

2001-12-05  Jonathan Larmour  <jlarmour@redhat.com>

        * src/dbg-threads-syscall.c (dbg_thread_syscall): Don't bother to
        deref a func ptr. The opcode could theoretically be 0x0!

2001-12-04  Richard Sandiford  <rsandifo@redhat.com>

        * src/generic-stub.c (__add_char_to_packet): Reverse check for
        end of buffer and end of packet to fix potential buffer overrun.

2001-12-01  Jonathan Larmour  <jlarmour@redhat.com>

        * src/dbg-threads-syscall.c (dbg_thread_syscall): check for
        NULL dbg_syscall_ptr.

        * src/hal_stub.c: Enable HAL_STUB_HW_SEND_STOP_REASON_TEXT for
        XScale architectures per Mark's request; XScale GDB needs to know
        what's happening with watchpoints (= work around previous change)

2001-11-29  Hugo Tyson  <hmt@redhat.com>

        * src/hal_stub.c: Condition out sending the reason for hardware
        watchpoint stop in the stop packet as $T05watch:01234568;... most
        GDBs do not understand it and in fact object to it.

2001-11-23  Nick Garnett  <nickg@redhat.com>

        * src/generic-stub.c (__process_packet): Fixed bogosity in
        handling of 'r' packet. It tried to send two replies, messing up
        the protocol and confusing GDB.

2001-11-02  Hugo Tyson  <hmt@redhat.com>

        * include/hal_stub.h (CYG_HAL_GDB_LEAVE_CRITICAL_IO_REGION):
        Permit this too to be defined externally ie. in a platform HAL.

2001-10-25  Gary Thomas  <gthomas@redhat.com>

        * cdl/hal.cdl: 
        * cdl/debugging.cdl: Reorg CDL a little so that GDB stub routines
        are only compiled when needed (instead of being compiled "empty").

2001-10-24  Gary Thomas  <gthomas@redhat.com>

        * cdl/hal.cdl: Add 'basic' test.

        * tests/basic.c: New test of some minimal HAL functionality.

        * cdl/debugging.cdl: CYGNUM_HAL_DEBUG_GDB_PROTOCOL_RETRIES is now
        defined as CDL 'data' flavor (tested via #if vs. #ifdef)

2001-10-17  Jesper Skov  <jskov@redhat.com>

        * src/generic-stub.c: Prefixed local version of memcpy and memset
        with _.

2001-10-17  Gary Thomas  <gthomas@redhat.com>

        * cdl/debugging.cdl: 
        * src/hal_if.c (cyg_hal_diag_mangler_gdb_putc): Make retry/abort optional,
        only attemped if CYGNUM_HAL_DEBUG_GDB_PROTOCOL_RETRIES is configured to
        be non-zero (default now 0).

2001-10-16  Jesper Skov  <jskov@redhat.com>

        * include/hal_stub.h: Allow ISOINFRA/LIBC to provide string
        functions.

2001-10-16  Gary Thomas  <gthomas@redhat.com>

        * include/generic-stub.h: Add prototypes for breakpoint_list functions.

        * src/thread-packets.c: Don't specify array sizes in extern decls.

        * src/hal_stub.c: Use HAL_STUB_REGISTERS_SIZE to set number of elements
        in register save areas. Default to NUMREGS if not defined by HAL.
        Allow HALs to provide specialized get_register()/put_register().

        * src/generic-stub.c (stub_format_registers): Support 'p' packet.
        (__process_packet): Rearrange ifdefs so error is sent for unsupported
        Z packet types.
        (process_query): Add hook for HAL specific queries.
        (process_set): Add hook for HAL specific sets.

        * include/generic-stub.h: Add extern decls to quiet compiler warnings.

2001-10-11  Gary Thomas  <gthomas@redhat.com>

        * include/generic-stub.h: 
        * src/generic-stub.c: Improve error handling more.  Make sure that
        packets are consumed, even if they are going to be tossed (overflow).
        This keeps TCP based connections going, even when the data is bad.
        (getpacket): Only send NAK in case of overflow.

2001-10-09  Jesper Skov  <jskov@redhat.com>

        * src/hal_if.c (flash_config_op): Protect with
        CYGARC_HAL_SAVE_GP.

2001-10-04  Jesper Skov  <jskov@redhat.com>

        * include/hal_endian.h: Added.
        Fix typo.

2001-10-03  Jonathan Larmour  <jlarmour@redhat.com>

        * include/hal_tables.h (CYG_HAL_TABLE_BEGIN): Use plain "object"
        because some (only some though) MIPS tools complain with %object.
        (CYG_HAL_TABLE_END): Ditto.

2001-10-02  Jonathan Larmour  <jlarmour@redhat.com>

        * include/hal_tables.h (CYG_HAL_TABLE_BEGIN): Use %object syntax
        rather than @object since @ is a comment character on ARM. gas
        accepts either syntax.
        (CYG_HAL_TABLE_END): Ditto.

2001-10-01  Gary Thomas  <gthomas@redhat.com>

        * src/generic-stub.c (getpacket): Send back error response (E01) if
        packet received which overflows buffers.  GDB doesn't always do much
        with this error, but at least it keeps the protocol moving.

2001-09-26  Gary Thomas  <gthomas@redhat.com>

        * cdl/common.cdl: New interface CYGINT_HAL_SUPPORTS_MMU_TABLES which
        indicates if the HAL supports MMU tables (few do).

2001-09-25  Gary Thomas  <gthomas@redhat.com>

        * cdl/common.cdl (CYGSEM_HAL_INSTALL_MMU_TABLES): Change to be
        default for ROM startup.

2001-09-20  Jesper Skov  <jskov@redhat.com>

        * tests/vaargs.c (cyg_start): Call CYG_TEST_INIT.

2001-09-10  Nick Garnett  <nickg@redhat.com>

        * include/hal_stub.h (strlen): Changed return type to size_t from
        int so it matches <string.h>. For some reason the compiler has
        suddenly started complaining about the type mismatch. Strange.

2001-09-07  Nick Garnett  <nickg@redhat.com>

        * src/hal_stub.c (put_register): Added kludge for VR4300 targets
        to sign extent the PC when it is being set. This is due to the
        age of the VR4300 toolchain and the fact that the VR4300 is the
        only target to do full 64bit register saves/restores.

2001-09-07  Jesper Skov  <jskov@redhat.com>

        * include/hal_if.h: Fix typo in below change.

2001-09-07  Jonathan Larmour  <jlarmour@redhat.com>

        * include/hal_if.h (CYGACC_CALL_IF_DBG_SYSCALL): Define and call
        with correct arguments.

2001-08-24  Mark Salter  <msalter@redhat.com>

        * src/generic-stub.c (__process_packet): Add support for 'D' packet.
        (__process_packet): Check for impossible mem write length.

2001-08-17  Jonathan Larmour  <jlarmour@redhat.com>

        * cdl/hal.cdl: Add CYGINT_HAL_VIRTUAL_VECTOR_COMM_BAUD_SUPPORT
        interface.

2001-08-16  Gary Thomas  <gthomas@redhat.com>

        * cdl/hal.cdl: Add CDL options to control GDB protocol retries.

2001-08-14  Gary Thomas  <gthomas@redhat.com>

        * src/hal_if.c (cyg_hal_diag_mangler_gdb_putc): Use timeout
        functions to allow for retries.  This should improve the case
        where [for whatever reason] the host GDB misses or ignores 
        a $O packet - it will get resent after a reasonable timeout.

2001-08-03  Gary Thomas  <gthomas@redhat.com>
2001-08-03  Jesper Skov  <jskov@redhat.com>

        * include/hal_if.h: Use inline functions for calls - allowing
        interrupts to be disabled while services are called
        [CYGACC_COMM_IF_CONTROL is an exception since it's using variable
        arguments - so it's still a macro].
        Pruned unused IF vectors: ICTRL_TABLE, EXC_TABLE, DBG_VECTOR,
        CPU_DATA, BOARD_DATA, SYSINFO, SET_SERIAL_BAUD.
        Note: this should fix bug CR 902745-CR.

        * cdl/hal.cdl: Removed CYGSEM_HAL_VIRTUAL_VECTOR_CLAIM_ICTRL.
        * src/hal_if.c (hal_if_init): Removed initialization of
        ICTRL_TABLE, EXC_TABLE, CPU_DATA and BOARD_DATA entries.

2001-08-03  Nick Garnett  <nickg@redhat.com>

        Imported from a development branch:
        
        2001-07-11  Nick Garnett  <nickg@redhat.com>

                * include/drv_api.h: 
                * src/drv_api.c:
                Added API for controlling routing of interrupts to CPUs in SMP
                configurations.

        2001-06-29  Nick Garnett  <nickg@cygnus.co.uk>

                * include/drv_api.h: 
                * src/drv_api.c:
                Added API for using spinlocks.

2001-08-03  Jesper Skov  <jskov@redhat.com>

        * tests/vaargs.c: Added.
        * cdl/hal.cdl: Added CYGPKG_HAL_BUILD_COMPILER_TESTS to allow cpp1
        and vaargs tests to be compiled conditionally.

2001-07-27  Jesper Skov  <jskov@redhat.com>

        * tests/intr.c: Set up interrupt ISR using driver API so it works
        properly in chained mode in the presence of arbiters.

        * src/drv_api.c (chain_isr): Call default ISR when
        appropriate. Return ISR return value.

        * include/hal_arbiter.h (hal_call_isr): Added version to be used
        with interrupt chaining.

2001-07-24  Mark Salter  <msalter@redhat.com>

        * cdl/hal.cdl (CYGINT_HAL_PLF_IF_IDE): New interface which
        indicates platform supports IDE controller I/F macros.

2001-06-29  Jonathan Larmour  <jlarmour@redhat.com>

        * cdl/hal.cdl (CYGPKG_HAL_TESTS): Remove redundant .c extension

2001-06-29  Jesper Skov  <jskov@redhat.com>

        * include/hal_misc.h: Moved arbiter helper to
        * include/hal_arbiter.h: this file to avoid header file inclusion
        order problems.

2001-06-28  Jesper Skov  <jskov@redhat.com>

        * include/hal_misc.h (hal_call_isr): Added. Used by ISR arbiters.

2001-06-22  Gary Thomas  <gthomas@redhat.com>

        * src/generic-stub.c (BUFMAX): Define as platform specific, thus
        reducing memory requirements.
        (__process_packet): Eliminate program arguments support until eCos
        makes use of them (more memory savings).

2001-06-22  Mark Salter  <msalter@redhat.com>

        * src/hal_stub.c (__do_copy_mem): Add goto statement to prevent
        compiler from moving instructions across 'err' label.

2001-06-14  Jonathan Larmour  <jlarmour@redhat.com>

        * src/generic-stub.c (__process_packet): Don't reset the board
        straight away with a 'r' packet. Let a 'k' packet do it instead.

        * src/hal_stub.c (__install_traps): Remove redundant comment.

2001-06-11  Jonathan Larmour  <jlarmour@redhat.com>

        * src/hal_if.c (delay_us): Revert below change of 2001-05-17

2001-06-05  Hugo Tyson  <hmt@redhat.com>

        * src/hal_if.c (cyg_hal_diag_mangler_gdb_putc): The nesting of
        CYGARC_HAL_SAVE_GP() and the instant-out if sending a carriage
        return "\r" was wrong - it scrambled the gp for the caller!  Since
        the return-test is trivial, I simply re-ordered rather than making
        the exit clause complex with a restore in it.

2001-05-17  Jonathan Larmour  <jlarmour@redhat.com>

        * src/hal_if.c (delay_us): Warn if using default

2001-05-14  Jonathan Larmour  <jlarmour@redhat.com>

        * cdl/interrupts.cdl (CYGNUM_HAL_COMMON_INTERRUPTS_STACK_SIZE):
        Default stack size to 32K for non-kernel configs, and describe
        why.

2001-05-07  Gary Thomas  <gthomas@redhat.com>

        * src/hal_if.c (hal_ctrlc_check): Only return 'true' if the ISR/DSR
        actually processes a ^C.  Otherwise, interrupts/date can be lost on
        a shared channel (like an ethernet device).

2001-04-30  Gary Thomas  <gthomas@redhat.com>

        * cdl/hal.cdl: Add configury to control initial cache behaviour.

2001-04-30  Hugo Tyson  <hmt@redhat.com>

        * cdl/hal.cdl: Add tests/cpp1.c to the tests list.

        * tests/cpp1.c: New test, to test for regressions in the tools.
        This one is for a CPP bug in the XScale tools where '+' binds too
        strongly following a ')' because it is mistaken for unary plus.

2001-04-25  Bart Veer  <bartv@redhat.com>

        * tests/cache.c:
        Fix test for cache presence.

        * src/drv_api.c (cyg_drv_interrupt_detach):
        Added missing indirection.

2001-03-28  Jonathan Larmour  <jlarmour@redhat.com>

        * include/dbg-threads-api.h: Add dbg_thread_id() function prototype.

2001-03-21  Mark Salter  <msalter@redhat.com>

        * src/hal_if.c (hal_if_init): Add explicit typecast when setting 
        version. Needed when sizeof(int) < sizeof(CYG_ADDRWORD).

2001-03-21  Jesper Skov  <jskov@redhat.com>

        * src/hal_if.c (hal_if_init): Added warning about debugging.

2001-03-20  Jonathan Larmour  <jlarmour@redhat.com>

        * include/hal_if.h: Add argument names to __call_if_flash_cfg_op_fn_t

2001-03-16  Mark Salter  <msalter@redhat.com>

        * src/hal_stub.c (__build_t_packet): Add hook for adding arch-specific
        registers to T packet.
        (handle_exception_cleanup): Skip orig_registers past breakpoint so we
        return to original context rather than hit breakpoint again.

2001-03-16  Hugo Tyson  <hmt@redhat.com>

        * include/hal_if.h: Define types and slots and macros themed with
        the phrase CALL_IF_FLASH_CFG_OP following the pattern of what's
        there for the other slots.  Thus CYGNUM_CALL_IF_FLASH_CFG_OP,
        CYGACC_CALL_IF_FLASH_CFG_OP(...) and __call_if_flash_cfg_op_fn_t
        are all newly defined.  Also CYGNUM_CALL_IF_FLASH_CFG_GET which is
        the only operation supported in this initial version.

        Also changed many typedef'd function pointers to not include the
        pointerness; that way the type can be used to validate the
        correctness of arguments in the called function.

        * src/hal_stub.c (__reset): Minor change to reset function
        handling; pointerness of typedef removed.

        * src/hal_if.c (flash_config_op): New function to call flash ops
        in RedBoot.  This is so that RedBoot can manage ethernet addresses
        for you, and the application can get at the data "cleanly".
        (hal_if_init): Install flash_config_op() in the table if defined.

2001-03-12  Mark Salter  <msalter@redhat.com>

        * src/hal_misc.c (cyg_hal_user_break): Use macro to find PC
        in saved regs.

        * src/generic-stub.c: Add support for harvard memories.
        * src/bplist-dynamic.c: Ditto.
        * include/generic-stub.h: Ditto.
        * include/hal_stub.h: Add dummy harvard memory macros for
        princeton memory systems.

2001-03-12  Jesper Skov  <jskov@redhat.com>

        * src/drv_api.c (cyg_drv_interrupt_detach): Fix missing intr->
        change.

2001-03-08  Jesper Skov  <jskov@redhat.com>

        * cdl/hal.cdl: Change sense of
        CYGINT_HAL_VIRTUAL_VECTOR_SUPPORT_GUARANTEED to new
        CYGINT_HAL_VIRTUAL_VECTOR_SUPPORT_NOT_GUARANTEED.

2001-03-07  Jesper Skov  <jskov@redhat.com>

        * src/drv_api.c: Use macro to provide symbol alias.

2001-03-05  Jesper Skov  <jskov@redhat.com>

        * src/hal_if.c (hal_if_diag_init): Ensure the function only
        executes once.

2001-03-02  Gary Thomas  <gthomas@redhat.com>

        * cdl/hal.cdl: 
        * include/hal_if.h: 
        * src/hal_if.c (hal_if_init): 
        Support platform specific initializations.

2001-02-26  Mark Salter  <msalter@redhat.com>

        * src/generic-stub.c (__process_packet): Change 'k' packet to cause
        return to original context. Change 'r' packet to respond with empty
        packet before resetting board.

        * src/hal_stub.c (handle_exception_exit): New function. Restores
        original context saved when stub was entered for the first time.
        (handle_exception_cleanup): Save original context.
        (__install_traps): Set __process_exit_vec to handle_exception_exit.

2001-02-09  Jesper Skov  <jskov@redhat.com>

        * cdl/debugging.cdl: Make CYGDBG_HAL_DEBUG_GDB_BREAK_SUPPORT and 
        CYGDBG_HAL_DEBUG_GDB_CTRLC_SUPPORT options have sensible defaults.

2001-02-08  Jesper Skov  <jskov@redhat.com>

        * cdl/hal.cdl: Added CYGSEM_HAL_VIRTUAL_VECTOR_INHERIT_CONSOLE and
        CHANNEL_CONFIGURABLE options.
        * cdl/common.cdl: Added CYGDBG_HAL_DIAG_TO_DEBUG_CHAN option.
        * src/hal_if.c: Changes to respect new options. Always do platform
        driver init from CLAIM_COMMS code.
        * src/hal_stub.c: Leave channel setup to CLAIM_COMMS code.

        * src/hal_if.c: Added null mangler that gets called via the
        virtual vector console comms entry and just forwards IO to the
        debug comms entries.  This differs from setting the console
        channel to the same as the debug channel in that console output
        will go to the debug channel even if the debug channel is changed.

2001-02-07  Jesper Skov  <jskov@redhat.com>

        * include/hal_if.h: Allow architecture to override COMM and CALL
        accessor macros.

2001-02-03  Gary Thomas  <gthomas@redhat.com>

        * src/bplist-dynamic.c (__set_breakpoint, __remove_breakpoint): 
        Fix error introduced below when no breakpoint list defined.

2001-02-02  Mark Salter  <msalter@redhat.com>

        * src/generic-stub.c: __set_breakpoint and __remove_breakpoint now
        take a length argument.

        * src/bplist-dynamic.c: Support breakpoint length. Use 
        HAL_BREAKINST_ADDR macro (if defined) to get actual breakpoint based
        on breakpoint length.

        * include/hal_stub.h: Add len argument to __set_breakpoint and
        __remove_breakpoint.

2001-02-01  Jesper Skov  <jskov@redhat.com>

        * src/drv_api.c: Make it build with chaining.

        * include/hal_if.h: Introduce macros for legal version range and
        special hacked version number used by ctrlc magic.
        * src/hal_if.c (hal_ctrlc_isr_init): Be more careful with how the
        version number is checked (and trashed) by the ctrlc init code.
        * src/hal_misc.c (hal_default_isr): Same.

        * src/hal_stub.c: Moved mangling code to hal_if.c
        * src/hal_if.c: New policies for when and how to initialize the
        IO channels. Mangler code now set up by diag_init to allow for
        mangling when no stub is included.

        * include/hal_if.h: Added COMM version in upper 16 bits of version
        word. Removed CYGPRI_HAL_IMPLEMENTS_IF_SERVICES.
        * src/hal_misc.c: Use masks when checking vv versions.

        * cdl/hal.cdl: Add new options for selecting which parts of the
        virtual vector table to initialize.
        * src/hal_if.c: Matching granularity in initialization code.
        Extra checking of services before using these.
        
        * cdl/debugging.cdl: Require channel initialization when enabling
        stubs.

2001-01-31  Jesper Skov  <jskov@redhat.com>

        * cdl/common.cdl: Get rid of CYGDBG_HAL_DIAG_DISABLE_GDB_PROTOCOL
        options. They are replaced by the CYGSEM_HAL_DIAG_MANGLER option.

2001-01-31  Hugo Tyson  <hmt@redhat.com>

        * include/hal_if.h: Make it possible to build logical ether driver
        even without virtual vectors present, by defining a dummy
        HAL_CTRLC_CHECK in that case; other code invokes it if debugging
        per se is enabled.

2001-01-26  Jesper Skov  <jskov@redhat.com>

        * src/hal_stub.c (__reset): Rename HAL_STUB_PLATFORM_RESETx macros
        to HAL_PLATFORM_RESETx.
        * src/hal_if.c (reset): Same.

2001-01-15  Nick Garnett  <nickg@cygnus.co.uk>

        * src/drv_api.c: Initialized isr_disable_counter to 1 so that it
        indicates that interrupts are initially disabled.

2000-12-15  Gary Thomas  <gthomas@redhat.com>

        * src/generic-stub.c: Define 'version' string to be a weak
        symbol that can be easily overridden (e.g. by RedBoot).

2000-12-11  Gary Thomas  <gthomas@redhat.com>

        * src/hal_if.c: Remove unnecessary (polluting) include file.

        * include/hal_stub.h: Support platform/variant supplied
        include files.  <cyg/hal/plf_XXX.h> can now be layered
        as <cyg/hal/var_XXX.h> which includes <cyg/hal/plf_XXX.h>.

2000-12-06  Jesper Skov  <jskov@redhat.com>

        * src/hal_if.c (delay_us): Ensure proper _GP save/restore.
        Reduce number of loops in fall-back code.

2000-12-05  Drew Moseley  <dmoseley@redhat.com>

        * src/hal_stub.c (__build_t_packet): Handle
        CYGARC_REGSIZE_DIFFERS_FROM_TARGET_REGISTER_T with Little Endian
        target.

        * include/hal_misc.h: Added BIT and SZ_ defines.

2000-11-22  Mark Salter  <msalter@redhat.com>

        * src/hal_misc.c (hal_default_isr): Version check only when
        CYGSEM_HAL_ROM_MONITOR not defined.

2000-11-20  Mark Salter  <msalter@redhat.com>

        * src/hal_stub.c (hal_flush_output): New function to flush debug
        comm interface.

        * src/generic-stub.c (__process_packet): Use hal_flush_output when
        killing or continuing.

        * include/hal_stub.h: Add declaration for hal_flush_output().

        * include/hal_if.h (__COMMCTL_FLUSH_OUTPUT): New comm control cmd.

2000-11-17  Jesper Skov  <jskov@redhat.com>

        * src/hal_if.c (delay_us): Add dummy loop.
        Duh! Take usecs argment into account.

2000-11-06  Mark Salter  <msalter@redhat.com>

        * src/generic-stub.c (__handle_exception): Add support for GNUPro bsp
        syscall handling.

        * src/board.h: Include pkgconf/redboot.h for CYGSEM_REDBOOT_BSP_SYSCALLS.

2000-11-06  Jesper Skov  <jskov@redhat.com>

        * src/hal_if.c (hal_if_diag_write_char): Clear interrupt flag before
        setting breakpoint.

2000-11-04  Mark Salter  <msalter@redhat.com>

        * src/hal_stub.c (__build_t_packet): Report reason and data
        address if stopped by hw watchpoint.

        * src/generic-stub.c (__process_packet): Remove experimental
        support for type 5 Z packet.

        * include/hal_stub.h: Define HAL_STUB_STOP_* reasons returned
        by HAL_IS_STOPPED_BY_HARDWARE.

        to align label
        (CYG_HAL_TABLE_TYPE): Define

2000-09-01  Jonathan Larmour  <jlarmour@redhat.com>

        * src/hal_stub.c (__build_t_packet): Ensure sign extension applies
        in the higher word, not the lower.
        (__build_t_packet): Don't need to conditionalize on

        problems with the current code.
        * src/generic-stub.c (stub_format_registers): Likewise

        * include/hal_if.h (CYGACC_COMM_IF_CONTROL): Remove warning due to
        unnecessary use of cpp paste operator

2000-08-28  Gary Thomas  <gthomas@redhat.com>

        * src/hal_if.c: 
        * include/hal_if.h (hal_ctrlc_check): Define new routine to be
        called by interrupt handlers (DSRs) which may be using hardware
        shared with a debug channel.  In particular, network adaptors 
        need to call this function to see if a ^C has occurred on the
        network debug connection.

2000-08-24  Gary Thomas  <gthomas@redhat.com>

        * include/hal_tables.h: Need descriminated tables (for proper sorting).

2000-08-14  Drew Moseley  <dmoseley@redhat.com>

        * src/hal_if.c: Added an extern declaration for
        cyg_hal_plf_comms_init.

        conflict.

2000-07-26  Gary Thomas  <gthomas@redhat.com>

        * src/hal_stub.c (cyg_hal_gdb_diag_putc): Ignore any characters
        other than the protocol chars of ACK/NAK/^C.

        * src/hal_if.c (hal_if_diag_init): Only reset console channel
        if user has configured a non-default choice.

2000-07-24  Drew Moseley  <dmoseley@redhat.com>

        * src/bplist-dynamic.c (__install_breakpoint_list): Call
        HAL_ICACHE_SYNC() rather than HAL_ICACHE_INVALIDATE_ALL().

2000-07-21  Drew Moseley  <dmoseley@cygnus.com>

        * src/hal_stub.c: Cleanup of #define's.

        * src/generic-stub.c: Rearrange the linkage between Cygmon and HAL so
        that Cygmon needs HAL but not vice-versa.  ie HAL no longer calls
        any Cygmon functions.
        * src/hal_misc.c: Ditto.

        * src/bplist-dynamic.c: Use HAL macros rather than Cygmon
        functions for flushing the cache.
        Also handle the case where target_register_t is not defined.

2000-07-21  Gary Thomas  <gthomas@redhat.com>

        * src/hal_if.c (CYGNUM_HAL_VIRTUAL_VECTOR_NUM_CHANNELS): Define to allow
        the number of channels to be extended by "AUX" packages.

2000-07-20  Drew Moseley  <dmoseley@redhat.com>

        * src/generic-stub.c (stub_format_registers): Make the previous patch
        effective only if CYGARC_REGSIZE_DIFFERS_FROM_TARGET_REGISTER_T is
        defined so as to not affect any other targets.
        * src/hal_stub.c: Ditto.

2000-07-19  Drew Moseley  <dmoseley@redhat.com>

        * src/generic-stub.c (stub_format_registers): Handle the case
        where GDB is expecting registers larger than we are storing.  ie
        MIPS gdb expects 64 bit registers even if we are on a 32 bit
        architecture.  Also, handle the sign-extension correctly if
        necessary.
        * src/hal_stub.c (__build_t_packet): Ditto.

2000-07-18  Jesper Skov  <jskov@redhat.com>

        * src/hal_misc.c (hal_default_isr): 
        Version gets hacked by hal_if_init - check for the hacked value.

2000-07-18  Jesper Skov  <jskov@redhat.com>

        * src/hal_stub.c (__mem_fault_handler): Made volatile.
        
2000-07-14  Drew Moseley  <dmoseley@redhat.com>

        * src/generic-stub.c: Cleanups for better coexistence with Cygmon.

        * cdl/hal.cdl: Compile bplist-dynamic.c.

        * src/bplist-dynamic.c: New file for supporting breakpoints in the HAL.

2000-07-14  Gary Thomas  <gthomas@redhat.com>

        * src/hal_if.c (delay_us): Use HAL_DELAY_US() if defined.

2000-07-07  Jesper Skov  <jskov@redhat.com>

        * src/hal_stub.c (initHardware): Fix #endif location.

        * src/hal_if.c (hal_ctrlc_isr_init): Added hack to work around a
        silly but critical problem.

        * src/hal_stub.c: Removed some CygMon conditional exclusions.

        * src/hal_if.c (hal_ctrlc_isr_init): Don't enable interrupts when
        configured as ROM monitor.

2000-07-05  Jesper Skov  <jskov@redhat.com>

        * cdl/debugging.cdl: Only allow CTRLC support if there's stubs or
        a ROM monitor to handle it. (Haruki Kashiwaya (kashiwaya at redhat
        dot com)).

2000-06-30  Jesper Skov  <jskov@redhat.com>

        * include/hal_if.h: Make CYGACC macros call functions. May have to
        add some _GET macros at some time if anyone needs to access the
        function pointers.

        * src/hal_stub.c: 
        * src/hal_misc.c:
        * src/hal_if.c:
        Matching changes of CYGACC clients.
        
2000-06-29  Jesper Skov  <jskov@redhat.com>

        * src/hal_stub.c (cyg_hal_gdb_diag_putc): Check console interrupt
        flag and breakpoint if set.

2000-06-28  Jesper Skov  <jskov@redhat.com>

        * src/hal_stub.c (cyg_hal_gdb_diag_putc): Don't try to set
        breakpoints in ROM startup - just disable interrupts. Also, use
        procs table function to disable device interrupts.

        * include/hal_if.h: Mark vector/comms arrays volatile to avoid
        compiler confusion.

        * include/dbg-threads-api.h: Fix C/C++ declaration issues.

        * src/hal_stub.c: Moved stub platform init call below vector table
        setup.

        * src/hal_misc.c:
        * src/hal_if.c:
        * include/hal_if.h: DBG_ISR_VECTOR and SET_TIMEOUT functions added
        to comms table. Added DELAY_US function to vector table. Made
        switching of debug channel dis/enable Ctrl-c interrupts as
        well. Made ctrlc_isr code use new vector entries. All this amounts
        to a properly switchable debug channel.

2000-06-21  Jesper Skov  <jskov@redhat.com>

        * src/hal_stub.c: Fixed clients of vector procs tables to pass
        in the correct arguments. Hook O-packetizer up on procs slot
        reserved for IO mangler. Install mangler when necessary.

        * src/hal_if.c: Extended set procs functions to allow temporarily
        switching console procs in a safe manner. Removed debug and
        console wrappers - all IO happens via drivers hooked up in tables
        rather than through hardwired macros. Proper initialization of
        console proc entry. Fixed clients of vector procs tables to pass
        in the correct arguments. Stub now does its own vector table
        initialization. Added special procs slot for IO manglers.

        * include/hal_if.h: Define special IDs used by the set procs
        functions. PROCS_HANDLED removed since the procs table will now
        always service any port.

2000-06-21  Nick Garnett  <nickg@cygnus.co.uk>

        * include/hal_stub.h: Added underscore to breakinst().

        * include/hal_tables.h:
        Added this file to contain macros for defining datatables in a
        systematic and extensible way.

2000-06-19  Gary Thomas  <gthomas@redhat.com>

        * cdl/hal.cdl: Revert change below - GUARANTEED can exist
        with STUBS defined.

2000-06-18  Gary Thomas  <gthomas@redhat.com>

        * cdl/hal.cdl: Use of virtual vector functions for diagnostic
        output must be disabled when building with stubs.  Note: this
        lets stubs be built for platforms with guaranteed virtual 
        vector support.

2000-06-16  Jesper Skov  <jskov@redhat.com>

        * include/hal_if.h: All vector-dependant features hidden when
        config option not enabled.

        * src/hal_if.c (hal_if_init): Fix warning.

2000-06-15  Jesper Skov  <jskov@redhat.com>

        * include/hal_if.h: Added console-include decision logic.

2000-06-15  Nick Garnett  <nickg@cygnus.co.uk>

        * src/drv_api.c: 
        * include/drv_api.h: Added boolean result to cyg_drv_cond_wait()
        to match change to the kernel and KAPI functionality.

2000-06-14  Jesper Skov  <jskov@redhat.com>

        * src/hal_stub.c: Added O-packetizer used by GDB stubs for virtual
        vector table configs.

        * src/hal_misc.c (hal_default_isr): Check Ctrlc for both CTRLC
        or BREAK options.

        * src/hal_if.c:
        * include/hal_if.h: 
        Define console wrappers when necessary. Platform HALs can use
        these by providing raw IO functions and some config data.

2000-06-09  Jesper Skov  <jskov@redhat.com>

        * src/hal_if.c: Implemented most of the remaining services. Some
        just don't have an eCos equivalent at the moment.

        * cdl/hal.cdl: Allow virtual_vector options to have sensible
        default values depending on when the platform HAL port was
        written.

        * src/hal_misc.c (cyg_hal_user_break): Also expect CygMon to
        provide the breakpoint service.

        * src/stubrom/stubrom.c (cyg_start): Reverted change. Now handled
        by hal_if_init.

        * cdl/hal.cdl: Added option for controlling use of diag services
        in the virtual vector table.

2000-06-08  Jesper Skov  <jskov@redhat.com>

        * src/stubrom/stubrom.c: Call hal_diag_init to ensure IF table
        entries related to diag IO get initialized.

        * src/hal_stub.c (cyg_hal_gdb_interrupt): save/restore GP so it
        can be used by MIPS platforms.
        Use reset function in ROM if available.

        * src/hal_misc.c: 
        * include/hal_misc.h: Functions shared between HALs. More
        functions are likely to be moved here if appropriate.

        * src/hal_if.c: Interfacing related functions: table init code and
        function wrappers.

        * include/hal_if.h: ROM/RAM calling interface table
        definitions. The layout is a combination of libbsp and vectors
        already in use by some eCos platforms.
        

        * cdl/hal.cdl: Added CYGxxx_HAL_VIRTUAL_VECTOR_SUPPORT
        options. These are used to control whether a platform uses the new
        ROM/RAM calling interface. All platforms will be converted to use
        this, but piecemeal over a period of time, thus the requirement
        for selecting behavior.

2000-06-04  Gary Thomas  <gthomas@redhat.com>

        * cdl/hal.cdl: Support variant 'pkgconf' headers.  This will allow
        [variant] common symbols to be defined, rather than duplicating 
        them over all platforms using that variant.

2000-05-25  Jesper Skov  <jskov@redhat.com>

        * cdl/debugging.cdl: Allow thread support to included for ROM
        monitor builds.

2000-05-22  Jesper Skov  <jskov@redhat.com>

        * cdl/debugging.cdl: Allow platform to prevent CTRLC inclusion.

2000-04-12  Jesper Skov  <jskov@redhat.com>

        * cdl/debugging.cdl: Don't let interfaces define anything.

2000-04-07  Jesper Skov  <jskov@redhat.com>

        * cdl/hal.cdl: Fix dependencies for stub.

2000-03-28  Jesper Skov  <jskov@redhat.com>

        * src/generic-stub.c (__process_packet): Added 'z' packet reply.

2000-03-28  John Dallaway  <jld@cygnus.co.uk>

        * cdl/hal.cdl:

        Adjust documentation URLs.

2000-03-24  Jesper Skov  <jskov@redhat.com>

        * include/hal_stub.h: Fixed a bad function name. Made it opssible
        for archs to define CYG_HAL_GDB_ENTER_CRITICAL_IO_REGION.

2000-03-20  Jesper Skov  <jskov@redhat.com>

        * cdl/debugging.cdl: Preclude USE_MONITOR when including stubs.

2000-03-01  Gary Thomas  <gthomas@cygnus.co.uk>

        * cdl/common.cdl: 
        Define CYGINT_HAL_DIAG_DISABLE_GDB_PROTOCOL_SUPPORTED as an
        'interface' so implementations can be properly specified.

2000-02-29  Gary Thomas  <gthomas@cygnus.co.uk>

        * cdl/common.cdl: Option to disable GDB protocol now supported
        by QUICC based PowerPC systems.

2000-02-29  Jonathan Larmour  <jlarmour@redhat.co.uk>

        * include/generic-stub.h: Make header C++ safe

2000-02-16  Jesper Skov  <jskov@redhat.com>

        * include/hal_stub.h: fixed endian definitions.

2000-02-10  Jesper Skov  <jskov@redhat.com>

        * include/pkgconf/hal.h: Added CYGSEM_HAL_ROM_MONITOR
        * src/hal_stub.c (initHardware): CYG_HAL_STARTUP_STUBS ->
        CYGSEM_HAL_ROM_MONITOR.
        Removed HAL_STUB_PLATFORM_STUBS_INIT.

2000-02-09  Jesper Skov  <jskov@redhat.com>

        * cdl/hal.cdl: Added remaining build dependencies.

2000-02-04  Jesper Skov  <jskov@redhat.com>

        * cdl/hal.cdl: Fix test list display.

2000-02-03  Jesper Skov  <jskov@redhat.com>

        * include/pkgconf/hal.h: CYG_HAL_POWERPC_x->CYGPKG_...

2000-02-03  Jesper Skov  <jskov@redhat.com>

        * cdl/debugging.cdl: Use interfaces for stub capabilities instead
        of exclude list.
        * cdl/hal.cdl: Add extra dependencies to common stub build rule.
        
2000-02-02  Jesper Skov  <jskov@redhat.com>

        * cdl/hal.cdl: Added HAL tests.

2000-01-31 Simon FitzMaurice  <sdf@cygnus.co.uk>
  * cdl/hal.cdl:

  Adjust help URLs in line with new doc layout.

2000-01-28 Simon FitzMaurice  <sdf@cygnus.co.uk>
  * cdl/hal.cdl:

  Adjust help URLs in line with new doc layout.

2000-01-27  Jesper Skov  <jskov@redhat.com>

        * cdl/hal.cdl: Added simple build rules for common stub.

2000-01-26  Jonathan Larmour  <jlarmour@redhat.co.uk>

        * src/hal_stub.c (__reset): Replace CYGDAT_CYGMON_ENABLE
        dependency with just CYGPKG_CYGMON
        (initHardware): Likewise
        (__set_baud_rate): Likewise
        (putDebugChar): Likewise

2000-01-17  John Dallaway  <jld@cygnus.co.uk>

        * cdl/common.cdl,
          cdl/debugging.cdl:

        Modify the default_value attribute for
        CYGFUN_HAL_COMMON_KERNEL_SUPPORT, CYGPKG_HAL_EXCEPTIONS
        and CYGDBG_HAL_DEBUG_GDB_THREAD_SUPPORT to do the right
        thing in the absence of the eCos kernel package.

1999-12-22  John Dallaway  <jld@cygnus.co.uk>

        * cdl/hal.cdl:

        Add CFLAGS to the custom rule for extras.o to accommodate
        arm big-endian targets.

1999-12-21  Jonathan Larmour  <jlarmour@cygnus.co.uk>

        * include/pkgconf/hal.h: Rename all CYG_HAL_USE_ROM_MONITOR_GDB_STUBS
        -> CYGSEM_HAL_USE_ROM_MONITOR_GDB_stubs
        Rename all CYG_HAL_USE_ROM_MONITOR_CYGMON -> 
        CYGSEM_HAL_USE_ROM_MONITOR_CygMon
        Rename all CYG_HAL_USE_ROM_MONITOR -> CYGSEM_HAL_USE_ROM_MONITOR
        Don't need to define CYG_HAL_SH_SH7708 any more

        * cdl/hal.cdl: Add CYGPKG_HAL_ROM_MONITOR container package for
        platforms to put ROM-monitor related options into
        Move all ROM-monitor related options into individual platform CDL

        * cdl\common.cdl: Correct example of illiteracy

1999-11-20  Gary Thomas  <gthomas@cygnus.co.uk>
        
        * cdl/common.cdl: Add MMU tables options.

        (CYGSEM_HAL_STATIC_MMU_TABLES): New options to control MMU table
        flavour and placement.

        * include/dbg-threads-api.h, include/generic-stub.h,
        include/hal_stub.h: Add comments to explain these header files should
        not be included by user programs

1999-11-09  Gary Thomas  <gthomas@cygnus.co.uk>

        * cdl/common.cdl: Add CYGDBG_HAL_DIAG_DISABLE_GDB_PROTOCOL.
        
        * include/pkgconf/hal.h (CYGDBG_HAL_DIAG_DISABLE_GDB_PROTOCOL): 
        New option which [explicitly] controls use of GDB protocol
        for diagnostic I/O.

        * src/hal_stub.c: Add explicit enable for CygMon package.

1999-10-27  Hugo Tyson  <hmt@cygnus.co.uk>

        * src/hal_stub.c (cyg_hal_gdb_interrupt): Bugfix to previous: ^Cs
        were being ignored when received by the diag output code, because
        there was already a break in place.  Solution is to let
        cyg_hal_gdb_interrupt() override any previous break, and tidy up
        state of course.

1999-10-26  Hugo Tyson  <hmt@cygnus.co.uk>

        * include/hal_stub.h (CYG_HAL_GDB_ENTER_CRITICAL_IO_REGION): Place
        the break at the address of a label within the calling context
        [normally hal_diag_write_char()]; this is neater and more
        portable; it's supported for more targets.  Also use
        cyg_hal_place_break() to place it, define that, &c.

        * src/hal_stub.c (cyg_hal_gdb_place_break): New routine to
        specially handle the inline breakpoint.  It basically does the
        same as cyg_hal_gdb_interrupt(), except on some platforms where
        you must do different things to set a bp from a non-interrupt
        context.

1999-10-25  Gary Thomas  <gthomas@cygnus.co.uk>

        * src/hal_stub.c (putDebugChar, getDebugChar): When building with
        CygMon, these functions are defined by CygMon.

        * cdl/hal.cdl:

        to the package version directory.

1999-10-22  Hugo Tyson  <hmt@cygnus.co.uk>

        * include/hal_stub.h (CYG_HAL_GDB_ENTER_CRITICAL_IO_REGION):
        (CYG_HAL_GDB_LEAVE_CRITICAL_IO_REGION): new macros to be invoked
        in hal_diag routines to make atomic the code that outputs a
        complete GDB $O packet.  This is required so that watching
        variables (which is implemented by stepping) and stepping itself
        does not try to ss through that $O output code.  CASE 102327.

        * src/hal_stub.c (cyg_hal_gdb_break_is_set): new routine to query
        whether a break is set: used by step in the stubs to decide to
        continue instead, because we are in a critical region.
        (cyg_hal_gdb_running_step): communication between generic stub and
        here: if set, a step has been converted into a continue, so we do
        NOT obey cyg_hal_gdb_remove_break until it is cleared, in
        handle_exception_cleanup().

        * src/generic-stub.c (__process_packet): If there is a break set
        by the hal_stub.c, convert a step to continue, and set
        cyg_hal_gdb_running_step to say we did so.

1999-10-22  Jesper Skov  <jskov@cygnus.co.uk>
        Case 102379
        * src/generic-stub.c (__handle_exception): Flush and clear caches
        after cleaning up after single-stepping.

        (memcpy, memset): Added to prevent stub hanging if user puts
        breakpoints in either function.

1999-10-19  Nick Garnett  <nickg@cygnus.co.uk>

        * include/pkgconf/hal.h: Added monitor configury for Brother

        * src/generic-stub.c: Reorg to expose register get/set functions.

1999-10-08  Simon Fitzmaurice <sdf@cygnus.co.uk>

1999-10-08  Jesper Skov  <jskov@cygnus.co.uk>

        * cdl/interrupts.cdl: Added

1999-09-22  Simon FitzMaurice <sdf@cygnus.co.uk>

        * cdl\hal.cdl : add priority field to "extras.o" rule

1999-09-15  Jesper Skov  <jskov@cygnus.co.uk>

        * src/hal_stub.c: Override generic GDB interrupt functions for
        ARM. Need them to be thumb aware. 

1999-09-13  Gary Thomas  <gthomas@cygnus.co.uk>

        * include/pkgconf/hal.h: Add new config option to allow spurious
        interrupts to be ignored by the HAL.

        * src/generic-stub.c (__process_packet): Build in version string
        (date/time) for stubs in ROM to be returned via 'd' packet.

1999-09-09  Jonathan Larmour  <jlarmour@cygnus.co.uk>

        * include/pkgconf/hal.h (CYGDBG_HAL_DEBUG_GDB_INCLUDE_STUBS): Rename
        CYGPKG_HAL_MN10300_SIM to CYGPKG_HAL_MN10300_AM31_SIM

1999-09-07  Nick Garnett  <nickg@cygnus.co.uk>

        * src/dbg-threads-syscall.c (dbg_currthread_id): Fixed to return
        zero if dbg_currthread() returns false. Previously it could have
        returned a random value which would have made GDB think there had
        been a thread switch when there hadn't. It was particularly prone
        to do this in configurations where the kernel was absent.

1999-09-01  Gary Thomas  <gthomas@cygnus.co.uk>

        * include/pkgconf/hal.h: Always include target and platform package
        include (pkgconf) files.

1999-08-26  Jonathan Larmour  <jlarmour@cygnus.co.uk>

        * src/generic-stub.c (__hex2mem_helper):
        Use target_register_t when casting to address type, rather than long
        Since the compiler can choose arbitrary alignment of unions, force
        to use byte array only
        Restore use of loop termination test for *hexMemSrc, just in case
        since that's how it used to be
        Increment destination, not source at end of loop
        
        (__mem2hex_helper):
        Use target_register_t when casting to address type, rather than long.
        Since the compiler can choose arbitrary alignment of unions, force
        to use byte array only. Therefore use single __read_mem_safe() call
        
        * src/hal_stub.c (__do_copy_mem): Reassign back from dst/src at start
        of each "if" clause in case we go round the loop again.

1999-08-24  Gary Thomas  <gthomas@cygnus.co.uk>

        * src/hal_stub.c (__do_copy_mem): Move temp variables to top of
        function - potentially safer if there is an error.

1999-08-23  Jonathan Larmour  <jlarmour@cygnus.co.uk>

        * src/generic-stub.c (__process_packet): For 'g' and 'G' packets,
        when the register size differs from sizeof(target_register_t) we must
        adjust according to the endianness 

        * include/hal_stub.h: Ensure __LITTLE_ENDIAN__ is defined on
        little-endian targets

        * src/hal_stub.c (__build_t_packet): Use the correct register sizes
        for PC and SP rather than assuming they are the same as target_register_t

1999-08-23  Gary Thomas  <gthomas@cygnus.co.uk>

        * include/generic-stub.h: Change prototypes for internal functions.

        * src/hal_stub.c (__do_copy_mem): 
        * src/generic-stub.c (__mem2hex_helper): Rework to perform aligned,
        multi-byte operations when conditions allow.  This should handle
        most "hardware register" access cases.  Note: there currently is
        no good way to force GDB to require/use such accesses.

1999-08-17  Jonathan Larmour  <jlarmour@cygnus.co.uk>

        * tests/intr.c (cyg_start): Use CYG_TEST_NA rather than a pass saying
        it's inapplicable

1999-08-16  Jonathan Larmour  <jlarmour@cygnus.co.uk>

        * include/pkgconf/hal.h: Rename CYG_HAL_MN10300_AM32_STDEVAL1 to
        CYG_HAL_MN10300_AM31_STDEVAL1

1999-08-13  Nick Garnett  <nickg@cygnus.co.uk>

        * src/hal_stub.c: Removed superfluous trace() extern.

1999-08-12  Nick Garnett  <nickg@cygnus.co.uk>

    1999-07-27  Nick Garnett  <nickg@cygnus.co.uk>

        * src/hal_stub.c: Added support for 1 byte breakpoints.
        Removed invalidates for cache flushes - I am not entirely sure why
        we have these here, since HAL_DCACHE_SYNC() should do what we
        need, and these invalidates are causing a problem on the MIPS and
        MN10300 targets.

        * include/pkgconf/hal.h: Added Monitor selection for AM33.

    1999-06-29  Nick Garnett  <nickg@cygnus.co.uk>

        * include/pkgconf/hal.h: Modified to match new MN10300 HAL
        organization.

1999-06-28  Jesper Skov  <jskov@cygnus.co.uk>

        * include/pkgconf/hal.h (CYGDBG_HAL_DEBUG_GDB_BREAK_SUPPORT):
        Fixed parent.

1999-06-24  Jonathan Larmour  <jlarmour@cygnus.co.uk>

        * include/pkgconf/hal.h: Clarify descriptions of
        CYGDBG_HAL_DEBUG_GDB_BREAK_SUPPORT and
        CYGDBG_HAL_DEBUG_GDB_CTRLC_SUPPORT.

1999-06-17  Nick Garnett  <nickg@cygnus.co.uk>

        * include/pkgconf/hal.h: Added CYGDBG_HAL_DEBUG_GDB_CTRLC_SUPPORT
        to enable inclusion of ^C interrupt handler. Added CDL to control
        it.

1999-06-10  Hugo Tyson  <hmt@cygnus.co.uk>

        * include/pkgconf/hal.h: Add support for the PowerPC target MBX860
        platform, CYG_HAL_POWERPC_MBX.

        * src/hal_stub.c (initHardware): Added call to
        HAL_STUB_PLATFORM_INIT if it is defined.

        * include/pkgconf/hal.h: Added a #undef for CYG_HAL_ROM_MONITOR,
        largely so that a stubrom permutation can define it.

1999-05-27  Nick Garnett  <nickg@cygnus.co.uk>

        * src/hal_stub.c: Do not call HAL_ICACHE_INVALIDATE_ALL() and
        HAL_DCACHE_INVALIDATE_ALL() in __instruction_cache() and
        __data_cache() for MIPS targets. These macros are simply
        duplicates.

1999-05-27  Jesper Skov  <jskov@cygnus.co.uk>

        * tests/cache.c:  Added handling of unified caches.

1999-05-25  Jonathan Larmour  <jlarmour@cygnus.co.uk>

        monitor from PMON.
        
1999-05-21  Jesper Skov  <jskov@cygnus.co.uk>

        * tests/intr.c: Get RTC values from CYGBLD_HAL_PLATFORM_H.
        Ensure there are fallback definitions.

        * src/hal_stub.c (handle_exception_cleanup): Added optional call
        of HAL_STUB_PLATFORM_STUBS_FIXUP macro.

1999-05-18  Jesper Skov  <jskov@cygnus.co.uk>

        * src/hal_stub.c (hal_output_gdb_string): Added missing ;

        * include/pkgconf/hal.h:
        tidied up all MIPS targets to include CYGBLD_HAL_TARGET_H. This
        will eventually apply to all configurations.

        * src/PKGconf.mak (COMPILE): Added dbg-threads-syscall.c.

        * include/dbg-thread-syscall.h: 
        * src/dbg-threads-syscall.c:
        Files added to enable support for thread-awareness in GDB stub
        ROMs. The .h file has been moved from kernel/src/debug.

    1999-04-28  Nick Garnett  <nickg@cygnus.co.uk>

        * src/hal_stub.c (__build_t_packet): Changed sp variable to a
        non-pointer type to force it to be installed in the T packet with
        the right size.

        * src/drv_api.c: Added cyg_interrupt_call_pending_DSRs() to keep
        HAL happy in non-kernel configurations.

    1999-04-21  Nick Garnett  <nickg@cygnus.co.uk>

        * include/pkgconf/hal.h:
        Added VR4300 configury for ROM monitor use and inclusion of
        variant-specific configuration header. This needs some further
        tidying up.
