Subject: * 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:
