* include/pkgconf/mlt_arm_arm9_excalibur_redboot.h: Added new
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.

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

startup configuration.
* src/excalibur_misc.c (hal_delay_us): Use timer.
* include/hal_platform_setup.h: Better ROMRAM startup.

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

* src/excalibur_misc.c (hal_delay_us): Don't use prescaling.
* include/hal_platform_setup.h: Set up EBI1-3 (flash parts 1-3) -
doesn't work though.

* src/excalibur_misc.c: Added debug code, disable PLD interrupts.
* include/hal_platform_setup.h: Added some (overkill) delays,
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.

(temporary) UART debug code. Fixing instruction addressing modes.

errors and warnings.
