* Patch by Marc Singer, 29 May 2003:

  Fixed rarp boot method for IA32 and other little-endian CPUs.

* Patch by Marc Singer, 28 May 2003:
  Added port I/O commands.

* Patch by Matthew McClintock, 28 May 2003
  - cpu/mpc824x/start.S: fix relocation code when booting from RAM
  - minor patches for utx8245

* Patch by Daniel Engström, 28 May 2003:
  x86 update

* Patch by Dave Ellis, 9 May 2003 + 27 May 2003:
  add nand flash support to SXNI855T configuration
  fix/extend nand flash support:
  - fix 'nand erase' command so does not erase bad blocks
  - fix 'nand write' command so does not write to bad blocks
  - fix nand_probe() so handles no flash detected properly
  - add doc/README.nand
  - add .jffs2 and .oob options to nand read/write
  - add 'nand bad' command to list bad blocks
  - add 'clean' option to 'nand erase' to write JFFS2 clean markers
  - make NAND read/write faster

* Patch by Rune Torgersen, 23 May 2003:
  Update for MPC8266ADS board
