Subversion Repositories openrisc

2003-04-10  Nick Garnett  <nickg@balti.calivar.com>

        * src/sh.ld:
        Added entry for .stack section in data section.

2003-01-31  Mark Salter  <msalter@redhat.com>

        * src/hal_syscall.c (hal_syscall_handler): Let generic syscall code
        handle exit.

2002-08-02  Andrew Lunn <Andrew.Lunn@ascom.ch>

        * cdl/hal_sh.cdl: The Redboot exec command can now be 
          disabled by CDL
        
2002-04-30  Jesper Skov  <jskov@redhat.com>

        * include/hal_var_sp.inc: Allow variant to provide custom
        interrupt vector layout. This means the size of
        hal_interrupt_handlers/objects/data can be reduced if the vector
        layout is sparse. Something similar could be done for
        _HW_EXEC_ENTRY_TABLE, saving exception_vector_int entries in the
        $vectors_code block. However, this code usually resides in flash
        so there's not much point given todays flash block sizes.

        * cdl/hal_sh.cdl: Added CYGHWR_HAL_SH_FPU and
        CYGHWR_HAL_SH_NO_FPU, allowing an arch level control of FPU
        related tests.
        Skipping test handled in a different way now, so the implements
        statement has been deleted again.

2002-04-29  Jesper Skov  <jskov@redhat.com>

        * include/hal_var_bank.inc: Define hal_exception_entry_extras and
        hal_interrupt_entry_extras.
        * include/hal_var_sp.inc: Define hal_exception_entry_extras and
        hal_interrupt_entry_extras. Disable interrupts on exception
        entry.
        * src/vectors.S: Call hal_exception_entry_extras and
        hal_interrupt_entry_extras.

2002-04-29  Jonathan Larmour  <jlarmour@redhat.com>

        * src/vectors.S:
        Don't use .file as it can confuse debugging since the .file
        doesn't contain the path and therefore the debugger will never
        know where it lives! This conflicts with using -Wa,--gstabs.

2002-04-15  Jonathan Larmour  <jlarmour@redhat.com>

        * src/hal_syscall.c (hal_syscall_handler): Add extra sig argument to
        __do_syscall.

2002-04-22  Jesper Skov  <jskov@redhat.com>

        * include/hal_var_sp.inc: 7044 needs different vector layout than
        76xx since its vectors are hardwired.

2002-04-18  Jesper Skov  <jskov@redhat.com>

        * include/hal_var_sp.inc: Do no translation of entry address if
        cache module defines CYGARC_SH_MOD_CAC_NO_WINDOWS.

        * include/hal_intr_vecs.h: Move all vectors after IRQ7 to variant
        header. Define _IRQ and _LVL for all of the first 7
        interrupts. Define CYGNUM_HAL_INTERRUPT_LVL_MAX

2002-03-06  Jesper Skov  <jskov@redhat.com>

        * include/hal_var_sp.inc: Fix asm comments.

2002-02-28  Jesper Skov  <jskov@redhat.com>

        * src/hal_syscall.c (hal_syscall_handler): Added.
        * src/sh_stub.c (__is_bsp_syscall): Added.
        * cdl/hal_sh.cdl: Build hal_syscall.c

2002-02-27  Jesper Skov  <jskov@redhat.com>

        * src/sh_stub.c (__computeSignal): Changed to use DATA_ACCESS
        names as well.
        * include/hal_intr_vecs.h (_CYGNUM_HAL_VECTOR_FIRST_MEM_FAULT,
        _CYGNUM_HAL_VECTOR_LAST_MEM_FAULT): Same.

2002-02-26  Jesper Skov  <jskov@redhat.com>

        ADDRESS_ERROR names.

2002-02-15  Jesper Skov  <jskov@redhat.com>

        * src/sh_stub.c (__single_step): Use normal breakpoint instruction
        (trapa #32) for single-stepping.
        On the SH2 the use of trapa#255 causes a different (and unhandled)
        exception, in the range reserved for application
        exceptions/interrupts.

2002-02-14  Jesper Skov  <jskov@redhat.com>

        * include/hal_var_bank.h: Switch mach/macl entries.
        * include/hal_var_sp.h: Same.

        * include/hal_var_sp.inc: Reserve (additional) trampoline for NMI
        to make eCos interrupt numbers match. Make traps use trap numbers
        32-64.
        (hal_cpu_save_regs): Remember to adjust SP for R0 save location.
        (hal_cpu_restore_regs_return): Rewritten to fix errors and allow
        SP to be changed from GDB.

2002-02-13  Jesper Skov  <jskov@redhat.com>

        * src/context.S (hal_thread_load_context): Load up stack pointer
        before enabling interrupts.
        
        * include/hal_var_sp.inc: Fetch the VSR pointer and jump to it
        instead of into the VSR table.
        (hal_cpu_restore_regs_return): adjust sp to point to exception
        state before returning.

        * include/hal_var_sp.inc: Moved _reset code to below vectors.

2002-01-17  Jesper Skov  <jskov@redhat.com>

        * include/hal_var_bank.inc: Include SH3 register references. Make
        better use of some delay slots.

        * src/vectors.S: Don't save exception/interrupt state on stack
        with debug markers. Load up event value in R4 before calling
        hal_intc_decode so it can be a nop if desired. Removed some SH3
        register references.

        * include/hal_var_sp.inc: Include SH2 offsets, export
        _HW_EXC_ENTRY_TABLE, fix some typos.

        * include/hal_intr_vecs.h: IRL vectors renamed. Added IRQ
        vectors.

2002-01-16  Jesper Skov  <jskov@redhat.com>

        * include/hal_var_bank.h: Fix typo.

        * src/sh_stub.c (__computeSignal): Only handle defined vectors.

        * include/hal_intr_vecs.h: Decode NMI as interrupt 0, moved all
        other vectors. Provide MEM_FAULT vector range.
        * include/hal_var_sp.inc: Changes for NMI-as-interrupt-0.
        * include/hal_var_sp.h: Renamed vector to event to share code.

        * include/hal_intr_excevt.h: Added MEM_FAULT vector ranges and
        CYGHWR_SH_RTC_TIMER_IS_TMU.
        * src/hal_misc.c (hal_delay_us): Only build if
        CYGHWR_SH_RTC_TIMER_IS_TMU. Use MEM_FAULT vector range.

        * include/hal_intr.h: Deleted clock controls.

        * cdl/hal_sh.cdl: Use CYGNUM_HAL_RTC_PRESCALE instread of
        module-specific prescale variable.

        * include/hal_intr_excevt.h (_CYGNUM_HAL_VECTOR_FIRST_MEM_FAULT,
        _CYGNUM_HAL_VECTOR_LAST_MEM_FAULT): Define.
        * include/hal_intr_vecs.h: Same. 
        * src/hal_misc.c (cyg_hal_exception_handler): Use new _MEM_FAULT
        vector range.


        * include/hal_intr_vecs.h: Removed RTC code.

        * include/hal_arch.h: Changed breakpoint instruction to match that
        used in GDB 5.1.
        It also makes better sense on the SH2.

        * include/hal_intr_excevt.h: Interrupt/exception vectors and clock
        handling code moved here...
        * include/hal_intr.h: From here.
        * include/hal_intr_vecs.h: Interrupt/exception vector layout +
        clock handling for SH1/SH2 variants.

        * include/hal_var_sp.inc: Added some comments, fixed number of
        pre-VSR vectors, renamed HW_VSR_TABLE to HW_EXC_ENTRY_TABLE to
        avoid confusion (it has nothing to do with eCos VSRs). Finally,
        made the pre-VSR stuff only compile when really required (since
        it's 4KiB).

2002-01-14  Jesper Skov  <jskov@redhat.com>

        * include/hal_arch.h: Moved HAL_SavedRegisters structure to
        bank variant headers. Same with HAL_THREAD_INIT_CONTEXT,
        HAL_THREAD_GET_SAVED_REGISTERS, HAL_GET_GDB_REGISTERS,
        HAL_SET_GDB_REGISTERS, CYGARC_BUS_ADDRESS, CYGARC_CACHED_ADDRESS,
        and CYGARC_UNCACHED_ADDRESS.

        for SH3/SH4 variants.
        * include/hal_var_bank.h: Added. Contains old hal_arch.h stuff for
        SH3/SH4 variants.

        from what the platform requests, using the new
        CYGINT_HAL_SH_PLF_LITTLEENDIAN_DEFAULT CDL interface.

        * src/sh.ld: Support .rel.got input sections.

2001-09-05  Jesper Skov  <jskov@redhat.com>

        * src/sh_stub.c (__single_step): Changed type 2 handling.

2001-08-22  Gary Thomas  <gthomas@redhat.com>

        * src/redboot_linux_exec.c: 
        printf() is no longer a part of RedBoot.  Thus all programs
        must use diag_printf() and related functions instead.

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

        * src/sh_stub.c: Fixed potential SH4 problem in UBC handling.

2001-06-19  Jesper Skov  <jskov@redhat.com>

        * src/redboot_linux_exec.c: Only base address, entry and cmdline
        options are always used. Other commands only affect image if
        set. This allows combined kernel&initrd images to be loaded in one
        file where the initrd address & size is already recorded at the
        start of the image.

        From YAEGASHI Takeshi <t@keshi.org> with a few changes:
        * cdl/hal_sh.cdl: Added RedBoot exec command options.

        SYM_PTR_REF. Brian Danilko spotted this.

2000-11-24  Jonathan Larmour  <jlarmour@redhat.com>

        * src/sh.ld: _reset should be adorned with CYG_LABEL_DEFN
        * src/vectors.S: CYG_LABEL_DEFN should have been used everywhere
        that CYG_LABEL_NAME was used, except for the scheduler lock which
        is special as it is defined in C as an asm alias.
        * include/arch.inc: Similarly here for symbol macros

        * include/basetype.h (CYG_LABEL_NAME): Delete. This is now obsolete.

2000-11-22  Jesper Skov  <jskov@redhat.com>

        the definition of inline immediate constants.

        * include/sh_regs.h: Include HAL config.

        * include/hal_arch.h: Don't prefix with _ in HAL_BREAKPOINT.
        * src/sh_stub.c: Matching changes - hack to handle both
        conventions.

        * include/basetype.h: Made CYG_LABEL_DEFN depend on toolchain.
