* Patch by Dan Malek, 07 Apr 2004:

  - Add support for RPC/STx GP3, Motorola 8560 board
  - Update 85xx TSEC driver so it searches MII for first available PHY
    and uses that one.
  - Add functions to support console MII commands.

* Patch by Tolunay Orkun, 07 Apr 2004:
  Move  initialization of bi_iic_fast[]
  from board_init_f() to board_init_r()

* Patch by Yasushi Shoji, 07 Apr 2004:
  Cleanup microblaze port

* Patch by Sangmoon Kim, 07 Apr 2004:
  Add auto SDRAM module detection for Debris board
