Yes it looks like this. I can see this split in all mpc85xx boards and
mpc8610 boards from Freescale. There just two boards where I don't see
this kind of split: holly & kurobox and I don't the have the reference
manual for both of them to check. I also don't have an OpenPIC spec to
check there.
So from this it looks like e500/e600 thing and FSL only so far.
