        * src/plf_misc.c: Likewise. Similarly CYG_HAL_USE_ROM_MONITOR_CYGMON
        -> CYGSEM_HAL_USE_ROM_MONITOR_CygMon

        * src/platform.S: Swapped around the IOPROF registers for
        big-endian mode. These 16 bit registers end up in opposite halves
        of the 32 bit word in big endian mode.

        * include/plf_z8530.h: In big-endian mode the Z8530 registers are
        at the other end of the word. This is easily fixed by redefining
        the DUART_BASE only.

1999-09-14  Jonathan Larmour  <jlarmour@cygnus.co.uk>

        * src/hal_diag.c (hal_diag_write_char): Ack VRC4373 interrupt to
        prevent spurious interrupts

        (hal_mon_init_vsr_table): Don't init debug vector - not used on
        vr4300 CPUs

1999-09-02  Nick Garnett  <nickg@cygnus.co.uk>

        * include/platform.inc: Added code to monitor setup to copy

        * src/platform.S: 
        Added function to read data from the PCI data register together
        with a data load/store VSR which catches any exceptions and fixes
        them up so that the program can continue.

1999-07-15  Jonathan Larmour  <jlarmour@cygnus.co.uk>

        * src/hal_diag.c: Add prototypes for cyg_hal_is_break and
        cyg_hal_user_break to silence warning

1999-06-21  Nick Garnett  <nickg@cygnus.co.uk>

        * src/plf_misc.c (hal_ctrlc_isr): Changed all return codes to 2 so
        that the interrupt is reported as handled.

        debug, utlb and nmi vectors.

        code.

        * src/platform.S:
        Made use of ROMRAM startup option where relevant.
        Modified code to be position independent since under ROMRAM
        startup it is linked to run in RAM but must actually run in ROM
        prior to the copy.
        Added some delay loops to try and get the hardware to settle on
        startup. Without these the machine sometimes wedges after
        power-on.

        * include/pkgconf/mlt_mips_vr4300_vrc4373_romram.ldi:

        * include/pkgconf/mlt_mips_vr4300_vrc4373_stubs.mlt:
        Added these files to support the new startup types.
        Note: at present the .mlt files do not match the .ldi files.

        * include/pkgconf/hal_mips_vr4300_vrc4373.h:
        Added ROMRAM and STUBS startup options to CDL. Moved default ports
        for DIAG and GDB to 0 at 38400 baud.
        Added an ifdef to modify the configuration for STUBS startup.

        * include/plf_stub.h: Removed spurious include.

        * include/platform.inc:
        Added version of INITIAL_SR for use with GDB stubs.
        Added implementation of "lar" macro and converted the relevant
        instances of "la" to use it.
        Made use of ROMRAM startup option where relevant.
        Implemented copy of ROM image to RAM and transfer of control to
        it.
        Tidied up trampoline copy and VSR table init in monitor init
        macros.
        Added code to generate messages to the GrammerEngine PromIce AI
        interface during initialization.

1999-05-20  Gary Thomas  <gthomas@cygnus.co.uk>

        * include/pkgconf/hal_mips_vr4300_vrc4373.h: Move RTC setup here.

        [VR4300 branch] 
        * include/pkgconf/mlt_mips_vr4300_vrc4373_rom.ldi:
        Moved RAM and ROM back to their correct addresses.

        * include/pkgconf/hal_vr4300_vrc4373.h: 
        * include/pkgconf/hal_mips_vr4300_vrc4373.h:
        Renamed hal_vr4300_vrc4373.h to match file name synthesized by
        pkgconf.tcl.

        * src/hal_diag.c:
        * src/plf_stub.c: 
        Removed explicit include of vrc4372 pkgconf file.

        * include/pkgconf/mlt_mips_vr4300_vrc4373_rom.ldi: For testing
        purposes ROM loaded code is put at 0x80680000 and its working RAM
        at 0x80600800. These will be moved back to the real addresses when
        we can build real ROMs.
        The corresponding .mlt file has NOT been changed.

        * src/plf_stub.c (hal_plf_init_serial): Re-enabled initialization

        * include/pkgconf/hal_vr4300_vrc4373.h: Add diag/gdb serial
        port configury.

1999-04-22  Nick Garnett  <nickg@cygnus.co.uk>

        [VR4300 branch] 
        * include/platform.inc: Modified hal_intc_init to always enable
        IPL0..2 bits in CP0 status register.

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

        [VR4300 branch]
        * src/plf_misc.c: Added this file to contain hal_platform_init().

        * src/pmon.S: Renamed pmon entry functions to avoid clashes with
        the C library. Removed unused code.

        * src/platform.S: Added this file. It contains an ISR springboard
        routine to decode interrupts via the vrc4372, a breakpoint
        springboard to allow breakpoints to continue being handled by
        PMON, and board specific versions of the ISR tables.
        [later] Fixed a bug in the ISR springboard, added a few comments
        too.
        
        * src/hal_diag.c: Implemented direct-to-hardware diagnostic
        output.

        * src/PKGconf.mak (COMPILE): Added platform.S.
        Added plf_misc.c.

        * include/plf_intr.h: Added extensive support for vr4372 interrupt
        controller.

        * include/platform.inc: Added an initial status register value to
        avoid upsetting PMON. Added plant of hal_breakpoint_springboard in
        VSR table. Added some diagnostic code to wiggle a led.
        Added an implementation of hal_intc_init. Changed initial status
        register value. Moved VRC4372 register definitions here.
