2003-12-05  Andrew Lunn  <andrew.lunn@ascom.ch>

        * include/hal_diag.h: hal_delay_us() is a C function.

2003-09-21  Gary Thomas  <gary@mlbassoc.com>

        * misc/redboot_RAM.ecm: 
        * misc/redboot_ROM.ecm: 
        * misc/redboot_ROMRAM.ecm:  Adjust for changes in RedBoot
        template - DNS now must be enabled manually.

2003-07-18  Nick Garnett  <nickg@balti.calivar.com>

        * cdl/hal_arm_ebsa285.cdl:
        Changed values for CYGNUM_HAL_RTC_NUMERATOR,
        CYGNUM_HAL_RTC_DENOMINATOR and CYGNUM_HAL_RTC_PERIOD to
        "default_value" from "calculated". This makes it easier
        to change these values globally.
        
2003-02-13  Patrick Doyle  <wpd@delcomsys.com>
        * src/ebsa285_misc.c: Replaced explicit prototype of memset with
        #include <string.h>.

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

        * src/redboot_cmds.c: Redboot exec command can now be disabled by CDL
        * cdl/hal_arm_ebsa285.cdl: Support needed for above.
        
2002-05-14  Jesper Skov  <jskov@redhat.com>

        * src/ebsa285_misc.c: Fixed warning.

2002-05-07  Gary Thomas  <gthomas@redhat.com>

        * cdl/hal_arm_ebsa285.cdl: 
        Standardize CYGNUM_HAL_VIRTUAL_VECTOR_CONSOLE_CHANNEL_DEFAULT usage.

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

        * src/mem285.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.

2002-04-26  Nick Garnett  <nickg@redhat.com>

        * misc/redboot_ROMRAM.ecm: Brought up to date with RAM and ROM ecm
        files.

2002-04-24  Jesper Skov  <jskov@redhat.com>

        * cdl/hal_arm_ebsa285.cdl: CYGPRI_KERNEL_TESTS_DHRYSTONE_PASSES
        defined.

2002-04-03  Gary Thomas  <gthomas@redhat.com>

        * misc/redboot_ROM.ecm: 
        * misc/redboot_RAM.ecm: Update for new RedBoot support, using generic
        network drivers.

2002-03-05  Jesper Skov  <jskov@redhat.com>

        * misc/redboot_ROM.ecm: Added dns+zlib packages.
        * misc/redboot_RAM.ecm: Same.

2002-01-28  Jesper Skov  <jskov@redhat.com>

        * cdl/hal_arm_ebsa285.cdl: Removed explicit plf_io.h declaration.

2001-11-02  Andrew Lunn  <Andrew.Lunn@ascom.ch>
2001-11-02  Jonathan Larmour  <jlarmour@redhat.com>

        * cdl/hal_arm_ebsa285.cdl: Add ROMRAM startup type and MLT file config.

        * include/hal_platform_setup.h: Support relocation of ROMRAM image.

        * include/pkgconf/mlt_arm_ebsa285_romram.h: New MLT files for romram.
        * include/pkgconf/mlt_arm_ebsa285_romram.ldi: Ditto.
        * include/pkgconf/mlt_arm_ebsa285_romram.mlt: Ditto.
        * include/pkgconf/mlt_arm_ebsa285_ram.mlt: Move app base to 0x30000 to
        allow for romram space.
        * include/pkgconf/mlt_arm_ebsa285_ram.ldi: Regenerate.

        * misc/redboot_ROMRAM.ecm: New file.

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

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

2001-06-21  Jonathan Larmour  <jlarmour@redhat.com>

        * images/*: Remove. Don't bloat repository with things already on
        the web.

2001-04-26  Hugo Tyson  <hmt@redhat.com>

        * misc/redboot_ROM.ecm: 
        * misc/redboot_RAM.ecm: Remove CYGSEM_HAL_VIRTUAL_VECTOR_DIAG from
        the import file; it's now calculated in the common HAL so no need
        to set it here.

2001-04-16  Gary Thomas  <gthomas@redhat.com>

        * cdl/hal_arm_ebsa285.cdl: Add CDL to describe CPU family.

        * cdl/hal_arm_ebsa285.cdl: Removed
        CYGINT_HAL_VIRTUAL_VECTOR_SUPPORT_GUARANTEED which is now the
        default.

2001-02-23  Jesper Skov  <jskov@redhat.com>

        * include/hal_cache.h (HAL_FLASH_CACHES_OLD_MACROS):  This platform
        uses deprecated cache handling macros.

2001-02-23  Gary Thomas  <gthomas@redhat.com>

        * misc/redboot_ROM.ecm: Renamed from redboot_ROM.cfg

        * misc/redboot_RAM.ecm: Renamed from redboot_RAM.cfg

2001-02-13  Gary Thomas  <gthomas@redhat.com>

        * src/ebsa285_misc.c (hal_IRQ_handler): 
        Return CYGNUM_HAL_INTERRUPT_NONE for spurious interrupts.

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

        * src/hal_diag.c: Replace CYGSEM_HAL_DIAG_MANGLER_None with
        CYGDBG_HAL_DIAG_TO_DEBUG_CHAN.

        * cdl/hal_arm_ebsa285.cdl: Respect channel configuration
        constraints.

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

        * src/hal_diag.c: Replaced CYGDBG_HAL_DIAG_DISABLE_GDB_PROTOCOL
        with CYGSEM_HAL_DIAG_MANGLER_None

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

        * src/hal_diag.c: Removed CYGSEM_HAL_VIRTUAL_VECTOR_DIAG check.
        * include/plf_stub.h: Moved reset macro to
        * include/hal_platform_ints.h: this file.

2001-01-03  Gary Thomas  <gthomas@redhat.com>

        * src/ebsa285_misc.c (hal_delay_us): Slight rearrangement to
        ensure this works properly on all speeds of platform.

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

        * cdl/hal_arm_ebsa285.cdl: 
        Enable CYGINT_HAL_VIRTUAL_VECTOR_SUPPORT_GUARANTEED - required
        to fully support RedBoot networking I/O and ^C.

2000-12-08  Jonathan Larmour  <jlarmour@redhat.com>

        * cdl/hal_arm_ebsa285.cdl: Build redboot_cmds.c in the right place.

2000-12-04  Hugo Tyson  <hmt@redhat.com>

        * include/hal_cache.h: Consistently ensure that ARM registers used
        in MCR ops to cache-control coprocessors, where the data doesn't
        matter, all actually have data zero ("SBZ") as in the Jaggar book.
        This may well not be necessary, but for the sake of making sure...

2000-12-01  Gary Thomas  <gthomas@redhat.com>

        * src/redboot_cmds.c: Add prototype to remove warning.

2000-11-30  Gary Thomas  <gthomas@redhat.com>

        * src/redboot_cmds.c (do_exec): Complete support for loading
        Linux, including use of an initial ramdisk image.

2000-12-01  Hugo Tyson  <hmt@redhat.com>

        * include/hal_cache.h: Define addressable cache line operations
        HAL_DCACHE_STORE(), HAL_DCACHE_INVALIDATE(), HAL_DCACHE_FLUSH()
        now that I have understood how come the test (kcache2) was
        failing.  See kernel ChangeLog for details.  Also tidied up a
        couple of other minor details.

2000-11-28  Drew Moseley  <dmoseley@redhat.com>

        * misc/redboot_RAM.cfg: Implement CYGSEM_REDBOOT_BSP_SYSCALLS.
        * misc/redboot_ROM.cfg: Ditto.

        * src/ebsa285_misc.c (ebsa285_program_new_stack): New function
        for switching to an application stack when running a program under
        a ROM monitor.

        * cdl/hal_arm_sa11x0_ebsa285.cdl: Define HAL_ARCH_PROGRAM_NEW_STACK.

2000-11-19  Gary Thomas  <gthomas@redhat.com>

        * cdl/hal_arm_ebsa285.cdl: Define CYGBLD_HAL_PLATFORM_IO_H.

        * src/redboot_cmds.c: Fix 'exec' command to handle Linux
        kernel.  Includes support to relocate image before startup.

        * cdl/hal_arm_ebsa285.cdl: Fix some minor comments.

2000-11-14    <gthomas@laptop_local>

        * include/hal_ebsa285.h (EBSA285_RAM_BANK0_BASE): Correct for SA110/285.

2000-11-13    <gthomas@laptop_local>

        * cdl/hal_arm_ebsa285.cdl: Fix out of date ROM/RAM description.

2000-10-18  Gary Thomas  <gthomas@redhat.com>

        * src/redboot_cmds.c: New file: only built in redboot, for a
        platform specific command to exec code with no MMU intervention.
        This is used to execute standard Linux kernels with as little
        change/perturbation as possible.

        * include/hal_ebsa285.h (EBSA285_RAM_BANK0_BASE): New symbol for
        redboot_cmds.c

        * cdl/hal_arm_ebsa285.cdl: Add build redboot_cmds.c -> libextras.

2000-09-17  Gary Thomas  <gthomas@redhat.com>

        * cdl/hal_arm_ebsa285.cdl: Add platform/cpu identification strings.

2000-09-06  Hugo Tyson  <hmt@cygnus.co.uk>

        * cdl/hal_arm_ebsa285.cdl (CYGHWR_HAL_ARM_EBSA285_PCI_MEM_MAP_BASE
        CYGHWR_HAL_ARM_EBSA285_PCI_MEM_MAP_SIZE): Add strong constraints
        to the alignment and size of the PCI window by means of
        legal_values lists so that runtime can check that the MLTs opinion
        of the memory usage is valid. [This is related to CR 902624-CR,
        "MLT needs to be configuration aware"]

        * include/pkgconf/mlt_arm_ebsa285_ram.h:
        * include/pkgconf/mlt_arm_ebsa285_ram.ldi:
        * include/pkgconf/mlt_arm_ebsa285_ram.mlt:
        * include/pkgconf/mlt_arm_ebsa285_rom.h:
        * include/pkgconf/mlt_arm_ebsa285_rom.ldi:
        * include/pkgconf/mlt_arm_ebsa285_rom.mlt:
        Regenerate these from the MLT featuring a "pci_window" section in
        order to prevent the greedy heap code comsuming all of memory.
        The pci_window section is from 0xf00000 of size 0x100000
        i.e. Megabyte number 15, at the top of (default) memory.
        Unfortunately my previous quick fix (2000-08-15) for this had not
        in fact worked, because of the "clever" code which looks for
        add-in memory and consumes *that* too, unconditionally...  [This
        is related to CR 902624-CR, "MLT needs to be configuration aware"]

2000-08-18  Hugo Tyson  <hmt@cygnus.co.uk>

        * include/hal_platform_setup.h: Initialize the world if you are
        blowing away previous state rather than only in ROM start.  This
        makes it possible to create a standalone RAM app that will work
        with either RedBoot in ROM or old-style GDB stubs, or any other
        loader you might find.

        Incidentally I now understand why Gary found it necessary to force
        PCI reset (2000-08-07) - with RedBoot in ROM, the RAM app was
        unconditionally reinitializing the PCI bus when it was already
        initialized, without resetting it.  We cannot play the same game
        here as with hal_platform_setup.h - I tried - because otherwise
        the net cannot re-initialize itself; the scan for devices fails.

2000-08-16  Hugo Tyson  <hmt@cygnus.co.uk>

        * include/hal_platform_setup.h (CYGHWR_LED_MACRO): Use an address
        that works for a customer's own not-quite-exactly-like an EBSA
        board.  It works fine on a real EBSA too of course.
        [CASE 104355]

2000-08-15  Hugo Tyson  <hmt@cygnus.co.uk>

        * include/pkgconf/mlt_arm_ebsa285_ram.h (CYGMEM_REGION_ram_SIZE):
        * include/pkgconf/mlt_arm_ebsa285_rom.h (CYGMEM_REGION_ram_SIZE):
        Do not "helpfully" consume all of memory for the heap, including
        PCI space, unconditionally; leave the PCI window alone.

2000-08-07  Gary Thomas  <gthomas@redhat.com>

        * include/plf_io.h (HAL_PCI_INIT): Force PCI reset, just for
        good measure.

2000-08-03  Gary Thomas  <gthomas@redhat.com>

        * src/ebsa285_misc.c (hal_delay_us): New routine, used for 
        hardware delays when no kernel timers are available.

        * include/hal_platform_setup.h (PLATFORM_SETUP1): Don't re-init
        hardware for RAM startup.  Doing so keeps network debugging from
        working (PCI gets shutdown, etc).

2000-07-25  Jonathan Larmour  <jlarmour@redhat.co.uk>

        * include/pkgconf/mlt_arm_ebsa285_ram.mlt: Add heap1 section for malloc
        * include/pkgconf/mlt_arm_ebsa285_ram.ldi: Regenerate
        * include/pkgconf/mlt_arm_ebsa285_ram.h: Regenerate
        * include/pkgconf/mlt_arm_ebsa285_rom.mlt: Add heap1 section for malloc
        * include/pkgconf/mlt_arm_ebsa285_rom.ldi: Regenerate
        * include/pkgconf/mlt_arm_ebsa285_rom.h: Regenerate

        * src/ebsa285_misc.c (hal_arm_mem_real_region_top): Remove warnings

2000-07-17  Jesper Skov  <jskov@redhat.com>

        * src/hal_diag.c (cyg_hal_plf_serial_isr): Return value was not
        always correct.

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

        * src/plf_stub.c: [deleted]
        * src/hal_diag.c:
        * src/ebsa285_misc.c: 
        * include/plf_stub.h: 
        * include/hal_platform_ints.h: 
        * include/hal_diag.h: 
        * cdl/hal_arm_ebsa285.cdl: 
        Changed to use virtual vector table.

2000-07-04  Jonathan Larmour  <jlarmour@redhat.co.uk>

        * cdl/hal_arm_ebsa285.cdl: This platform implements
        CYGINT_HAL_ARM_MEM_REAL_REGION_TOP

        * src/ebsa285_misc.c (hal_arm_mem_real_region_top): Add to allow
        true memory sizes to be reported, for the benefit of dynamic memory
        systems

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

        * include/hal_platform_setup.h: 
        'hal_dram_size' is now a properly defined variable (no more
        fixed 0x40 stuff).

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

        * include/pkgconf/mlt_arm_ebsa285_ram.ldi: 
        * include/pkgconf/mlt_arm_ebsa285_ram.mlt: 
        * include/pkgconf/mlt_arm_ebsa285_rom.ldi: 
        * include/pkgconf/mlt_arm_ebsa285_rom.mlt: 
        Incorporate new fixed vectors (used on all ARM platforms).

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

        * include/pkgconf/mlt_arm_ebsa285_ram.h:
        * include/pkgconf/mlt_arm_ebsa285_ram.ldi:
        * include/pkgconf/mlt_arm_ebsa285_ram.mlt:
        * include/pkgconf/mlt_arm_ebsa285_rom.h:
        * include/pkgconf/mlt_arm_ebsa285_rom.ldi:
        * include/pkgconf/mlt_arm_ebsa285_rom.mlt:
        Align all sections on word boundaries

2000-02-24  Hugo Tyson  <hmt@cygnus.co.uk>

        * src/mem285.S (__mem285_init): Re-do the SDRAM initialization
        until a consistent answer is acquired twice in a row.  We have
        been seeing test failures with the SDRAM initialization in the
        board with 32Mb - the SDRAM setup is screwey; hope this fixes it.

2000-02-21  Gary Thomas  <gthomas@cygnus.co.uk>

        * cdl/hal_arm_ebsa285.cdl: Remove -mstructure-size-boundary=8
        option - no longer needed to build working network code.

2000-02-18  Jonathan Larmour  <jlarmour@redhat.co.uk>

        * cdl/hal_arm_ebsa285.cdl (CYGBLD_BUILD_GDB_STUBS): When
        building stubs, define every dependency required here rather than
        in the template

2000-02-10  Hugo Tyson  <hmt@cygnus.co.uk>

        * include/hal_cache.h (HAL_ICACHE_INVALIDATE_ALL):
        (HAL_DCACHE_INVALIDATE_ALL): Also invalidate TLBs in case the
        reason for the cache invalidate is a MM table rewrite.

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

        * include/plf_stub.h:
        HAL_STUB_PLATFORM_STUBS_INIT->HAL_STUB_PLATFORM_INIT
        
        * src/hal_diag.c: 
        * misc/stubrom.perm:  [removed]
        * misc/STUBS_config:  [added]
        * include/pkgconf/hal_arm_ebsa285.h: 
        Removed stubs as a legal startup type.

2000-02-09  Hugo Tyson  <hmt@cygnus.co.uk>

        * cdl/hal_arm_ebsa285.cdl (CYGBLD_GLOBAL_CFLAGS): Permanently set
        the -mstructure-size-boundary=8 compilation option, as required by
        the initial version of the OpenBSD network stack port, currently
        software under development.

2000-02-07  Jesper Skov  <jskov@redhat.com>

        * cdl/hal_arm_ebsa285.cdl: Use cpu option when linking.

2000-02-04  Hugo Tyson  <hmt@cygnus.co.uk>

       * include/hal_platform_setup.h (INIT_XBUS_ACCESS): 
       (CYGHWR_LED_MACRO): Fix a typo - "and" alone doesn't set
       conditions, so branch depending on "PCI arbiter enabled" was taken
       randomly.

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

        * cdl/hal_arm_ebsa285.cdl: Implements stubs.

2000-01-31  Hugo Tyson  <hmt@cygnus.co.uk>

        * include/hal_ebsa285.h: Correct misleading comment.

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

        * cdl/hal_arm_ebsa285.cdl: Moved part of stubs build rule to
        common HAL. Changed description.

2000-01-26  Jesper Skov  <jskov@cygnus.co.uk>

        * cdl/hal_arm_ebsa285.cdl: Removed below. Target does not have
        CygMon support.

2000-01-25  Jesper Skov  <jskov@cygnus.co.uk>

       * cdl/hal_arm_ebsa285.cdl: Added cygmon console device
       config. Added make rule for binary conversion of cygmon image.

2000-01-24  Jesper Skov  <jskov@cygnus.co.uk>

        * cdl/hal_arm_ebsa285.cdl: Add stubs build rule.

2000-01-24  John Dallaway  <jld@cygnus.co.uk>

        * cdl/*.cdl:

        Remove obsolete option CYGTST_TESTING_IDENTIFIER.

2000-01-19  Hugo Tyson  <hmt@cygnus.co.uk>

        * cdl/*.cdl: Add descriptions to a number of options &c which were
        lacking same, also tidied up other typos as noticed en passant.

2000-01-10  Hugo Tyson  <hmt@cygnus.co.uk>

        * src/ebsa285_misc.c (hal_IRQ_handler): Conditionally remove
        debugging check for FIQ sources being active at customer's
        request; they are now using FIQ via VSR so the warning message is
        unwanted.

1999-11-25  Jonathan Larmour  <jlarmour@cygnus.co.uk>

        * src/hal_diag.c: Conditionalize def of diag_buffer for only when it's
        explicitly wanted and someone hacks the code
        (hal_diag_write_char): Likewise

1999-11-25  Gary Thomas  <gthomas@cygnus.co.uk>

        * include/pkgconf/mlt_arm_ebsa285_rom.h: 
        * include/pkgconf/mlt_arm_ebsa285_ram.h: Update 'do not edit' strings.

1999-11-16  Hugo Tyson  <hmt@cygnus.co.uk>

        * tests/sdram0.cxx: New file to test SDRAM initialization.  It is
        somewhat EBSA specific in that it sanity checks the control reg
        setup as well as testing memory per se.

        * cdl/hal_arm_ebsa285.cdl: build the new test.

        * tests/PKGconf.mak: New file: build the new test.

1999-11-16  Hugo Tyson  <hmt@cygnus.co.uk>

        * src/mem285.S: Rewrite, essentially: it was the only way to get a
        good enough handle on what this nasty, trick stuff does.  I'm very
        happy with it now.  It's also callable for RAM startup too, to
        happily count up the RAMs as initialized: no guessing ever again!

        * include/hal_platform_setup.h: Delete some code!  Now that mem285
        initialization is sorted out, it's cool to do exactly the same
        thing for ROM and RAM startup; the mem init code differs, mind, to
        just add up the memory sizes in RAM start.

1999-11-10  Hugo Tyson  <hmt@cygnus.co.uk>

        * include/hal_platform_setup.h (PLATFORM_FLUSH_DISABLE_CACHES):
        Also flush TLBs - this is vital when changing cachability &c
        during startup.  Also do that same flush in ROM start, for when we
        build to run in flash block #1 following POST executing, when
        "stuff" might be in an odd state.

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

        * include/pkgconf/mlt_arm_ebsa285_ram.h:

        * src/ebsa285_misc.c: 
        Remap PCI accessible memory as non-cachable. Changed default
        PCI mapped memory to the top 1MB of a 16MB system.

1999-11-01  Jesper Skov  <jskov@cygnus.co.uk>

        * cdl/hal_arm_ebsa285.cdl: Remove define_proc comments.

1999-10-29  Jesper Skov  <jskov@cygnus.co.uk>

        * include/pkgconf/mlt_arm_ebsa285_ram.ldi:

        * include/pkgconf/mlt_arm_ebsa285_ram.mlt: 
        * include/pkgconf/mlt_arm_ebsa285_rom.mlt: 
        Increased memory size to 16MB.
        
1999-10-27  Jesper Skov  <jskov@cygnus.co.uk>

        * src/hal_diag.c: Fixed conditional include.

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

        * src/hal_diag.c (hal_diag_write_char): Use new macro
        CYG_HAL_GDB_ENTER_CRITICAL_IO_REGION and its mate to control
        stepping through gdb $O packet output.

1999-10-26  Jesper Skov  <jskov@cygnus.co.uk>

        CYGBLD_GLOBAL_COMMAND_PREFIX

1999-10-20  John Dallaway  <jld@cygnus.co.uk>

        * cdl/hal_arm_ebsa285.cdl:
        Define build-related and memory layout-related CDL options.

        * include/plf_io.h:
        * include/pkgconf/hal_arm_ebsa285.h: 
        Added configurability of EBSA memory accessible from PCI space.

        * src/ebsa285_misc.c (hal_bsp_mmu_init): Folded XBus into 21285 regs.

        Define CYGTST_TESTING_IDENTIFIER.

1999-10-05  Hugo Tyson  <hmt@cygnus.co.uk>

        * support/linux/safl_util/sa_flash.c: Add a lot of extra
        diagnostics and some new options; did this in the course of
        finding out whether a board really was dead or not, so may as well
        commit it.

1999-09-24  Jesper Skov  <jskov@cygnus.co.uk>

        * include/plf_io.h (HAL_PCI_INIT): Fix rookie code bug.

        * include/hal_ebsa285.h (SA110_XBUS_XCS2): Fix typo.

1999-09-01  Hugo Tyson  <hmt@cygnus.co.uk>

        * include/hal_ebsa285.h (ARM_MMU_SECTION): Move these macros and
        memory-layout structure definitions here from ebsa285_misc.c so
        that others can use them.

        * src/ebsa285_misc.c (hal_IRQ_handler): Scan FIQ sources also and
        print a warning if any are active.
        (hal_hardware_init): Clear the FIQ enable mask at startup too;
        this was assumed to be cleared at reset, but just in case...
        (ARM_MMU_SECTION): Move these macros and memory-layout structure
        definitions from here to include/hal_ebsa285.h so that others can
        use them.
        
        * src/hal_diag.c (hal_diag_write_char): Do not unconditionally
        poke the XBUS LED location - XBUS may not be available if internal
        21285 arbiter is in use.
        (hal_diag_write_char): Fix warnings for proto of
        cyg_hal_gdb_interrupt().
        
1999-09-01  Jesper Skov  <jskov@cygnus.co.uk>

        * include/plf_io.h (HAL_PCI_CONFIG_ADDRESS): Use alternate config
        space 0 addressing so all 32 devices can be scanned.

1999-08-27  Jesper Skov  <jskov@cygnus.co.uk>

        * include/hal_ebsa285.h: Added some timer bits.

1999-08-24  Jesper Skov  <jskov@cygnus.co.uk>

        * include/hal_ebsa285.h (SA110_XBUS_CYCLE_ARBITER_ENABLED): Added.

        * include/hal_platform_setup.h (INIT_XBUS_ACCESS): Check jumper
        settings and behave accordingly.

        * include/plf_io.h (HAL_PCI_TRANSLATE_INTERRUPT): Fixed interrupt
        vector table to match observed behavior.

1999-08-19  Jesper Skov  <jskov@cygnus.co.uk>
        PR 20326

1999-08-19  Jesper Skov  <jskov@cygnus.co.uk>

        * include/hal_platform_setup.h (BASIC_PCI_SETUP): [+untabified]
        * include/plf_io.h (HAL_PCI_INIT): 
        Changed PCI enable comment to match actual behavior.

1999-08-17  Jesper Skov  <jskov@cygnus.co.uk>

        * include/plf_io.h: Rename HAL_PCI_CONFIG_INTERRUPT to
        HAL_PCI_TRANSLATE_INTERRUPT.
        Read _PIN instead of _LINE.

1999-08-16  Jesper Skov  <jskov@cygnus.co.uk>

        * include/plf_io.h (HAL_PCI_CONFIG_INTERRUPT): Added.

1999-08-13  Jesper Skov  <jskov@cygnus.co.uk>

        * include/plf_io.h: Renamed macros and added resource information.
        Renaming again.
        
1999-08-12  John Dallaway  <jld@cygnus.co.uk>

        * cdl/hal_arm_ebsa285.cdl:
        Define CYG_HAL_STARTUP and CYGHWR_MEMORY_LAYOUT.

1999-08-12  Jesper Skov  <jskov@cygnus.co.uk>

        * include/plf_io.h: Added PCI macros.

1999-08-12  Jesper Skov  <jskov@cygnus.co.uk>

        * cdl: Added CDL for ebsa.

1999-08-12  Jesper Skov  <jskov@cygnus.co.uk>

        * include/hal_platform_setup.h: 
        * include/hal_ebsa285.h: 
        Renamed some PCI registers and moved out generic PCI stuff.

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

        * include/hal_ebsa285.h: Added more definitions.

        * include/plf_stub.h (HAL_STUB_PLATFORM_RESET): Defined.

1999-08-04  Jesper Skov  <jskov@cygnus.co.uk>

        * src/ebsa285_misc.c (ARM_ACCESS_TYPE_x): each domain has two bits.

1999-07-26  John Dallaway  <jld@cygnus.co.uk>

        * include/pkgconf/mlt_arm_ebsa285_rom.mlt: 
        * include/pkgconf/mlt_arm_ebsa285_ram.mlt: 

        Fix memory section alignments to match those of the pre-built
        linker script fragments.

1999-07-26  Hugo Tyson  <hmt@cygnus.co.uk>

        * include/pkgconf/mlt_arm_ebsa285_rom.mlt: 
        * include/pkgconf/mlt_arm_ebsa285_ram.mlt: 
        Make these match the .ldi files that do the linking proper, so
        that the process is reversible and the .ldi files recreatable.

1999-07-26  Hugo Tyson  <hmt@cygnus.co.uk>

        * include/hal_platform_ints.h (CYGDBG_HAL_CTRLC_ISR): Define this
        if needed so that the arch HAL can conditionally call our poll
        routine.  Problem is that CYGDBG_HAL_DEBUG_GDB_CTRLC_SUPPORT *is*
        defined for platforms that do not support it.

1999-07-23  Hugo Tyson  <hmt@cygnus.co.uk>

        * src/hal_diag.c (hal_ctrlc_isr): Define this function, which is
        called from the default ISR, if CYGDBG_HAL_DEBUG_GDB_CTRLC_SUPPORT
        is defined.  It looks for a ^C in the serial input and bangs out
        with a breakpoint if one arrives.  Note that you cannot do much at
        all after this bp, except examine the stack and see where the
        program had got to.
        (hal_diag_write_char): Do not eat response characters from GDB:
        leave them for the ISR mentioned above to test for ^C.

        * src/ebsa285_misc.c (hal_hardware_init): Unmask the interrupt for
        serial reception, so that we can scan for incoming ^C, if the
        option CYGDBG_HAL_DEBUG_GDB_CTRLC_SUPPORT is defined.

1999-07-23  Hugo Tyson  <hmt@cygnus.co.uk>

        * include/hal_platform_ints.h (CYG_GDB_DEV_INT, CYG_DIAG_DEV_INT):
        define these so that interrupting using ^C and so on will work.

1999-07-22  Hugo Tyson  <hmt@masala.cygnus.co.uk>

        * support/README: New file.
        * support/linux/README: New file.
        * support/linux/safl_util/README: New file.
        * support/linux/safl_util/Makefile: New file.
        * support/linux/safl_util/sa_flash.c: New file.
        * support/linux/safl_util/safl.c: New file.
        Keep the devo safl_utils for programming ebsa-285 FLASH in the
        eCos tree too, so that it gets into our releases.

1999-07-21  Hugo Tyson  <hmt@cygnus.co.uk>

        * include/hal_platform_setup.h (PLATFORM_SETUP1): Get ROM startup
        to work OK; tidy up RAM start in consequence.  Do not set
        CYGHWR_HAL_ARM_HAS_MMU so that we jump straight into high ROM.
        Remove consequently unused macros.

        * src/ebsa285_misc.c: Pass DRAM size as detected at startup around
        correctly; worry less about alignment of MMU page table thingy.

        * src/hal_diag.c: Make ROM startup systems output in clear.

        * src/mem285.S: Get rid of all that IMM() nonsense.

        * misc/stubrom.perm: NEW FILE: Add instructions for making a STUBROM.

        * include/pkgconf/mlt_arm_ebsa285_rom.ldi: Get the numbers right
        for ROM startup.

1999-07-19  Hugo Tyson  <hmt@masala.cygnus.co.uk>

        * src/mem285.S: New file: offers routine __mem285_init, for DRAM
        sizing before the MMU is set up.  Code borrowed from CygMon/BSP of
        course.

        * src/ebsa285_misc.c: Add the meat of the 'C' initialization here;
        MMU initialization is the main addition.  Code borrowed from
        CygMon/BSP.

        * src/PKGconf.mak (COMPILE): Add mem285.S, which contains tricky
        DRAM sizing and init code - which of course can only be run from
        ROM, since it is damaging to the contents of DRAM.

        * include/hal_platform_setup.h (PLATFORM_SETUP1): Add required
        startup code in various macros to make constructing one phrase for
        ROM vs RAM startup easier, and for debug.  Code borrowed from
        CygMon/BSP.

        * src/hal_diag.c (hal_diag_init): Initialize the hardware, by
        setting the baud rate.

        * include/hal_ebsa285.h (ARM_FIRST_LEVEL_PAGE_TABLE_SIZE): Add
        this and a few other symbols for the DRAM sizing and MMU init
        code.

1999-07-16  Hugo Tyson  <hmt@cygnus.co.uk>

        * include/pkgconf/hal_arm_ebsa285.h: Typo in tidy up of config
        info.  Doh!

1999-07-16  Hugo Tyson  <hmt@cygnus.co.uk>

        * include/pkgconf/hal_arm_ebsa285.h: Tidy up config info.

1999-07-15  Hugo Tyson  <hmt@cygnus.co.uk>

        * src/ebsa285_misc.c (hal_hardware_init): Enable the caches in
        here; they are now disabled during startup.

        * include/hal_platform_setup.h (PLATFORM_SETUP1): Added code to
        disable caches [if RAM start] and switch to the ROM address
        [regardless, since it's the RAM addr if RAM start so harmless]

        * include/pkgconf/mlt_arm_ebsa285_rom.ldi: Set up some of the
        values here while they are in my head; see above.

1999-07-15  Hugo Tyson  <hmt@cygnus.co.uk>

        * include/hal_cache.h: Tidy up cache macros and make semantics
        better match what the GDB stubs require.

1999-07-15  Hugo Tyson  <hmt@cygnus.co.uk>

        * include/sa-110.h: removed, it was added in error.  Its contents
        live in include/hal_ebsa285.h

1999-07-14  Hugo Tyson  <hmt@cygnus.co.uk>
