I haven't even found how you're supposed to switch to big-endian mode.
They mention that there's a BIGEND signal to the core, but there's no
indication of how you'd set it. Perhaps yet another feature that didn't
work, so it was dropped halfway through the design.

Hmm, I wonder if it might be BWSCON[0] :-)

Heh, at least for 2440, we should be safe - if you look at the register
map, there's a lot of registers that change address if going big-endian.
And of course, there's no provision in the kernel for easily switching
those addresses.
