The natural byte order for the Power Architecture is Big Endian. We do
not support Littel Endian mode on Power.
I have to admit that I doubt if efforts to implement LE mode on
Power make any sense - as mentioned, BE is the natural byte order, and
usually it's much easier to explicitly convert date when accessing LE
devices as we're doing for example when accessing the PCI bus.
I recommend to reconsider your plans.
Best regards,
Wolfgang Denk
