CFG_8266ADS flavour of MPC8260ADS port was not tested (as mentioned in README) because I haven't got a board, but due to similarity in boards architecture you may be able to run it with minor changes. First of all, MPC8266-PCI hasn't got Local bus SDRAM so undefine CFG_LSDRAM_BASE in MPC8260ADS.h. After this the board may boot. Another problem is flash support. MPC8266-PCI uses different flash so you will have to clone flash support from other boards supporting AMD flashes. All other boards of MPC260ADS family use Sharp flashes which are supported. If the current code boots, you'll have no support for writing to flash. PCI bridge in target mode is not supported by current ports AFAIK. MPC8260ADS port does not support PCI at all.
