* Patch by Rick Bronson, 16 Mar 2003:
Add support for Atmel AT91RM9200DK w/NAND
* Patches by Robert Schwebel, 19 Mar 2003:
- use arm-linux-gcc as default compiler for ARM
- fix i2c fixup code
- fix missing baudrate setting
- added $loadaddr / CFG_LOAD_ADDR support to loadb
- moved "ignoring trailing characters" _before_ u-boot wants to
print out diagnostics messages; removes bogus characters at the
end of transmission
* Patch by John Zhan, 18 Mar 2003:
Add support for SinoVee Microsystems SC8xx boards
* Patch by Rolf Offermanns, 21 Mar 2003:
ported the dnp1110 related changes from the current armboot cvs to
current u-boot cvs. smc91111 does not work. problem marked in
smc91111.c, grep for "FIXME".
* Patch by Brian Auld, 25 Mar 2003:
Add support for STM flash chips on ebony board
* Add PCI support for MPC8250 Boards (PM825 module)
