* Patches by Jon Diekema, 15 Sep 2003:
- add description for missing CFG_CMD_* entries in the README file
- sacsng tweaks:
include/configs/sacsng.h:
+ Support extra bootp options like: 2nd DNS and send hostname
+ Enabling ping and irq command
+ Adding defines for a bunch of misc configrabled options
(patches for these options will be coming)
+ Adding watchdog support, but it isn't enabled yet.
board/sacsng/sacsng.c:
+ Suppressing unneeded output when the quiet environment
is non-zero.
+ show_boot_progress() now accepts any negative number as a
failure code.
+ show_boot_progress() flashes the error code 5 times, and
then resets the board to retry the boot from the top
* Patch by Gleb Natapov, 14 Sep 2003:
enable watchdog support for all MPC824x boards that have a watchdog
