* Patch by Rune Torgersen, 13 Feb 2003:
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
