        REDBOOT startup mode that is similar in function to the ROMRAM
        starup mode, with the exception that (RedBoot) application memory
        is linked at 0x07f80000 instead of 0x00008000, thus freeing up
        memory at 0x8000 to applications linked without the correct linker
        map.

        * src/excalibur_misc.c (hal_clock_initialize): Be a little more
        careful initializing the timer.

        workaround here.

        * src/excalibur_misc.c (hal_IRQ_handler): INT_ID doesn't do the
        helpful thing, so decode by steam.

        * cdl/hal_arm_arm9_excalibur.cdl: Disable D-cache again.

2001-08-14  Jesper Skov  <jskov@redhat.com>

        * src/excalibur_misc.c (hal_mmu_init): Don't let flash be cached:
        appears to cause a bus lock when accessed from RAM.

        * include/hal_platform_setup.h: Only copy code when in ROMRAM
        startup configuration.

        * src/excalibur_misc.c (hal_delay_us): Use timer.

        * include/hal_platform_setup.h: Better ROMRAM startup.

        * include/pkgconf/mlt_arm_arm9_excalibur_romram.h: Added.

        * src/hal_diag.c: Use RI flag in ISR instead of polling the FIFO
        count register. Appears that FIFO jams on overruns somehow, and
        messes up the ISR state in the process. Try to work around that by
        checking both FIFO count and ISR RI flag. It works. Sort of.

        * src/excalibur_misc.c (hal_delay_us): Do nothing for now. Real
        code changed a bit too. 

        * include/excalibur.h: Fixed typo in FIFO register defs.

        * cdl/hal_arm_arm9_excalibur.cdl: Changed baud rate to 9600 until
        cache issue is resolved.

        * include/hal_platform_setup.h: Set up EBI1-3 (flash parts 1-3) -
        doesn't work though.

        * include/hal_platform_ints.h: Added reset code.

        * include/excalibur.h: Added watchdog defs. Updated EBI regions.

2001-08-09  Jesper Skov  <jskov@redhat.com>

        * include/hal_platform_setup.h: Remove SRAM hack.
        * include/excalibur.h: Same.

        moved PLD mmap init, do SDRAM init, don't touch unused mmap
        entries. Do DPSRAM init (not that it should make a difference).

        * include/excalibur.h: Fixed mmap sizes. Fixed SDRAM map
        size. Added some debug code. Added DPSRAM defs.

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

        * include/hal_platform_setup.h: Jump to ROM, disable ROM
        mapping. Wait after SDRAM refresh operations.
        Output debug via LED macro.

        * include/excalibur.h: Altera SDRAM settings.

        * include/hal_platform_setup.h: Adding more initialization and
        (temporary) UART debug code. Fixing instruction addressing modes.

        * include/excalibur.h: Adding more definitions.

        * cdl/hal_arm_arm9_excalibur.cdl: Added ihex build rule for
        RedBoot.

        * include/hal_platform_setup.h: Set up memory map.

        * include/excalibur.h: Added memory mapping registers and memory
        map layout.

        * cdl/hal_arm_arm9_excalibur.cdl: Package display changed to match
        top-level. Added clock definitions (must add configury eventually).
