There's basically only two cases: if we have a builtin flat tree, we
pass that and NULL in r5; if we don't, and we have OF, we pass NULL in
r3 and the OF entry point in r5.  I think that could be handled in
main.c.

We also lost the "enforce minimum address only for 64-bit" thing in
the translation, too.

I believe that just patch 1/6 on its own won't give us a working
zImage, so we'll have to split up the changes differently when it
comes time to check this stuff in to git.

Paul.
