Nah.  Little-endian, with a 32-bit bus swizzle.  This is not the
same thing as big-endian when not all your registers are 32 bits.

Also, you can only write 32 bits, they don't use byte enables.

The question is if the device is close enough to OHCI to declare it
as that in the device tree.  I would say "yes".
