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.
