* 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) * Patch by Stefan Roese, 25 Mar 2003:
