The PowerPC documentation lists bit 0 as MSB. For a 32 bit value, bit
31 is the LSB.

Now _BYTE_order is something completely different. For your  question
it  does  not  matter  at  all [FYI: U-Boot is (except for eventually
remaining bugs) byteorder-independent].


The bit order doesn't matter, either. Just write down  the  constants
as listed in the manual - MSB as MSB down to LSB as LSB ;-)
