Coming back to the specific pxa25x_udc case: using __raw_* accessors
in the driver would possibly end up breaking the PXA25x machines in
the (very unlikely) case that someone wants to make it work with
big-endian kernels, assuming it does not have the same hardware
byteswap logic as ixp4xx.
As far as I know, pxa25x machine implies the kernel is little endian. From an
hardware perspective, pxa25x doesn't support big endian (old ARM platform).

So I don't think considering BE for pxa25x is ... necessary.

Cheers.
