The PowerPC documentation lists bit 0 as MSB. For a 32 bit value, bit 31 is the LSB.
It seems like not to know this is incredibly stupid as I couldn't find anything about byte order in the README or the u-boot manual.
Anyway, if anyone could please tell me something about the byte-order of the u-boot code and how it relates to MPC-manual-byte-order, I'd be very happy.
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 ;-)
