* Patch by Rune Torgersen, 13 Feb 2003:LABEL_2003_03_06_0200

  Add support for Motorola MPC8266ADS board

* Patch by Kyle Harris, 19 Feb 2003:
  patches for the Intel lubbock board:
  memsetup.S - general cleanup (based on Robert's csb226 code)
  flash.c - overhaul, actually works now
  lubbock.c - fix init funcs to return proper value

* Patch by Kenneth Johansson, 26 Feb 2003:
  - Fixed off by one in RFTA calculation.
  - No need to abort when LDF is lower than we can program it's only
    minimum timing so clamp it to what we can do.
  - Takes function pointer to function for reading the spd_nvram. Usefull
    for faking data or hardcode a module without the nvram.
  - fix other user for above change
  - fix some comments.

* Patches by Brian Waite, 26 Feb 2003:
  - fix port for evb64260 board
  - fix PCI for evb64260 board
  - fix PCI scan

* Patch by Reinhard Meyer, 1 Mar 2003:
  Add support for EMK TOP860 Module

* Patch by Yuli Barcohen, 02 Mar 2003:
  Add SPD EEPROM support for MPC8260ADS board
