That should be possible. I guess I'll need that in the future, too
for MPC8540.

I have a little MPC8540ish raw test driver kernel 2.6 module which
allows to access something on the Local Bus via GPCM as well as via
UPM. It was a useful thing to experiment around.

Feel free to contact me if you want to have it.
