        * src/hal_arch.S: in the interrupt VSR only lock the scheduler in

        kernel configurations.

        * include/hal_intr.h (hal_interrupt_handlers): add a define'd

        alias for cyg_hal_interrupt_handlers, needed by objloader.

        * include/arch.inc: include some debug info in assembler functions

        * cdl/hal_m68k.cdl, tests/iram1.c: add test for on-chip memory and

        the iram linker script section.

2008-02-14  Bart Veer  

        * include/hal_io.h: cope with being #include'd from inside a

        linker script.

        * include/hal_intr.h: fix HAL_VSR_SET() macro for

        autoincrement/decrement pointer argument. Fix HAL_DELAY_US()

        support for cached vs. uncached execution.

2007-02-04  Bart Veer  

        * src/plf_stub.h (HAL_STUB_PLATFORM_INIT_SERIAL): do not both with

        plf_comms_init() if the virtual vector init code has already taken

        care of it.

2006-12-21  Bart Veer  

        *  src/m68k.ld: ensure the ctors table is properly aligned.

2006-12-13  Bart Veer  

        * src/m68k.ld: default to placing _stext at the start of

        .m68k_startup instead of .text, but allow platforms to override

        this.

        * src/vectors.S: minor code size optimizations to the startup

        code.

2006-12-03  Bart Veer  

        * src/vectors.S: allow platforms to suppress the exception vector

        entries in .ram_vectors while preserving the virtual vectors and

        any variant/processor/platform-specific data.

        * include/hal_cache.h: allow indirect inclusion from assembler

        files.

2006-10-12  Bart Veer  

        * src/m68k.ld (SECTION_iram): fix alignment problems when the

        on-chip code is not a multiple of 4 bytes

2006-10-11  Nick Garnett  

        * src/m68k.ld: Removed a stray '.' from _EH_FRAME1_. Added

        _region_ argument to _EH_FRAME1_ and _GCC_EXCEPT_TABLE1_.

2006-09-25  Bart Veer  

        * doc/m68k.sgml: update to reflect recent changes in the M68K

        HALs.

2006-09-25  John Dallaway  

        * cdl/hal_m68k.cdl: Restore CYGBLD_LINKER_SCRIPT - required by the

        eCos Configuration Tool.

2006-09-13  Jonathan Larmour  

        * src/vectors.S: Place hal_m68k_exception_reset in its own

        section, to avoid its section being at 0x0 which confuses

        GDB.

2006-09-10  Bart Veer  

        * cdl/hal_m68k.cdl: there is no need for the linker script to be

        an option.

        * cdl/hal_m68k.cdl, src/plf_stub.h: allow the architectural HAL to

        provide plf_stub.h at the platform HAL's request, to avoid lots of

        duplication of the same header.

2006-09-08  Bart Veer  

        * src/m68k.ld: greatly simplify M68K linker script support. Add

        support for on-chip RAM.

        * src/vectors.S: tidy up. Add support for on-chip RAM.

        * src/hal_m68k.c: move hal_if_init() up the hierarchy

        * include/hal_io.h: can now be safely #include'd by assembler

        files.

        * include/hal_arch.h: change gdb stub target_register_t definition

        to avoid compiler warning.

2006-09-05  Bart Veer  

        * src/vectors.S: fix fencepost bug in BSS initialization

        * src/m68k.ld: discard exception-related sections unless libstdcxx

        is in the configuration.

        * src/hal_m68k.c: remove idle thread action function, now defaults

        to just an empty macro.

        * src/hal_arch.S: tidy up comment.

        * include/hal_intr.h: HAL_VSR_SET() is now optional.

        * include/hal_cache.h: fix default cache definitions.

        * include/hal_arch.h: allow lower-level HAL to provide the LSBIT

        and MSBIT macros. Do not initialize interrupts in a thread context

        when building RedBoot, so loaded applications start with ints

        disabled.

        * cdl/hal_m68k.cdl: fix custom build rules for proper dependency

        handling.

2006-07-10  Bart Veer  

        * src/m68k.ld, src/vectors.S: distinguish cleanly between the

        exception vectors and the startup code. Add support for mcf52xx

        cfm flash security settings.

        * src/hal_m68k.c: rationalize hal_arch_default_isr() &

        hal_default_isr() functions

        * cdl/hal_m68k.cdl, src/hal_arch.S, include/arch.inc: default to

        providing startup/interrupt stack in the architectural HAL

        * include/hal_intr.h: default to providing HAL_DELAY_US() in the

        architectural HAL

2006-06-26  Jonathan Larmour  

        * cdl/hal_m68k.cdl: Use correct syntax for modern GNU tail.

2006-03-10  John Dallaway  

        * cdl/hal_m68k.cdl: Add reference to M68k architecture documentation.

2006-02-21  Bart Veer  

        * include/hal_intr.h (HAL_ENABLE_INTERRUPTS): fix

        DEFAULT_IPL_LEVEL usage.

2005-06-10  Jonathan Larmour  

        * src/m68k.ld: gcc_except_table subsections don't need to be

        kept.

2005-06-03  Jonathan Larmour  

        * src/m68k.ld: gcc_except_table needs to be marked KEEP.

2005-05-23  Jonathan Larmour  

2005-05-23  Bart Veer  

        * src/hal_arch.S (hal_m68k_exception_handler): Zero frame pointer

        to improve GDB backtraces.

        (hal_interrupt_stack_call_pending_DSRs): Ditto.

        * src/vectors.S (hal_m68k_exception_reset): Use shorter suba.l

        instruction to zero frame pointer.

2005-02-17  Jonathan Larmour  

        * src/m68k.ld: Use CYGBLD_HAL_LINKER_GROUPED_LIBS from the common HAL

        for GROUP() list now.

2004-10-22  Bart Veer  

        * src/hal_m68k.c (hal_m68k_startup): add more init macros if the

        platform needs them.

        * doc/m68k.sgml: document the various init macros

2004-09-22  John Dallaway  

        * src/m68k.ld: Add got, frame and RELOCS sections. Accommodate .bss*

2004-06-24  Bart Veer  

        * src/vectors.S: extend fixed_vectors with sections for the

        variant, processor and platform HALs. This makes it easier to

        share data between RedBoot and the application.

        * src/hal_m68k.c (hal_m68k_startup): support init routines

        provided by the variant and processor HALs.

2004-02-11  Bart Veer  

        * src/vectors.S: give .fixed_vectors the right section attributes,

        and fix comment.

        * src/hal_arch.S (hal_m68k_interrupt_vsr): use new macro

        hal_context_extract_isr_vector_shl2, saving an instruction in the

        main interrupt handling path.

        * doc/m68k.sgml: document new macro

        hal_context_extract_isr_vector_shl2

2004-01-09  John Dallaway  

        * cdl/hal_m68k.cdl:

        Correct capitalisation of "Variant details" string.

2004-01-05  Bart Veer  

        * src/hal_m68k.c (cyg_hal_invoke_constructors):

        This function should not be static. In some configurations it may

        get called from the libc startup code.

2003-09-30  Bart Veer  

        * src/hal_arch.S: __profile_mcount() was referenced even if the

        profiling package was absent. This was only a problem when

        building without linker garbage collection.

2003-09-26  Bart Veer  

        * cdl/hal_m68k.cdl, src/hal_arch.S, doc/m68k.sgml:

        The architectural HAL now provides mcount profiling support.

2003-08-01  Bart Veer  

        * src/hal_arch.S: rework VSR and

        hal_interrupt_stack_call_pending_DSRs so that interrupts are only

        re-enabled while running the DSR, not elsewhere in the interrupt

        handling code. Currently this is the only way to guarantee that

        stack usage remains bounded.

        * src/hal_m68k.c: define new variable hal_m68k_dsr_ipl_level,

        the IPL level that should be used when running DSRs.

        * include/hal_intr.h: HAL_INTERRUPT_STACK_CALL_PENDING_DSRS() is

        now defined even when not running with an interrupt stack, so that

        DSRs still run with interrupts enabled.

        * doc/m68k.sgml: Minor updates following changes to the interrupt

        handling.

        * include/hal_arch.h (HAL_THREAD_INIT_CONTEXT): A thread would be

        initialized with the wrong status register value if the default

        IPL level was not zero

2003-07-22  Bart Veer  

        * doc/m68k.sgml: Fix various typos etc.

2003-07-17  Bart Veer  

        * doc/m68k.sgml: update documentation.

2003-07-06  Bart Veer  

        * src/hal_arch.S: Add support for kernel interrupt

        instrumentation.

2003-07-04  Bart Veer  

        * src/hal_arch.S:

        Rework interrupt and exception VSR's to make the use of an

        interrupt stack optional, and to allow interrupt nesting to be

        disabled.

        * src/hal_m68k.c:

        * src/vectors.S:

        hal_m68k_interrupt_nesting count is no longer required. Instead

        the stack pointer itself is compared with the interrupt stack base

        and top when deciding whether or not to switch to the interrupt

        stack.

        * include/hal_intr.h:

        HAL_INTERRUPT_STACK_CALL_PENDING_DSRS() is only provided if there

        is an interrupt stack

        * include/hal_arch.h:

        Adjust stack sizes for different interrupt-related configurations

        * cdl/hal_m68k.cdl:

        Interrupt stacks and nesting are now optional as on other

        architectures.

2003-06-25  Bart Veer  

        * include/hal_arch.h:

        Eliminate a build warning.

        * include/hal_intr.h:

        Provide default implementation of HAL_TRANSLATE_VECTOR()

2003-06-04  Bart Veer  

        * New version of the M68K support
