Patch by Jon Loeliger, 16 Jul 2004:
- support larger DDR memories up to 2G on the PC8540/8560ADS and STXGP3 boards - Made MPC8540/8560ADS be 33Mhz PCI by default. - Removed moldy CONFIG_RAM_AS_FLASH, CFG_FLASH_PORT_WIDTH_16 and CONFIG_L2_INIT_RAM options. - Refactor Local Bus initialization out of SDRAM setup. - Re-implement new version of LBC11/DDR11 errata workarounds. - Moved board specific PCI init parts out of CPU directory. - Added TLB entry for PCI-1 IO Memory - Updated README.mpc85xxads
