Having two different device trees for the different firmwares is
pretty yucky, and could be a pain in the bum for synchronization of
fixes.  Can't you have a common tree, and just poke the places that
are differently configured by the two firmwares from the bootwrapper.

A helper function that adjusts soc, localbus, pci and whatever else is
necessary based on the immrbase could be useful for other fsl
platforms, too.
