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
