I looked a the openbios code this morning. For all intents and purposes
the values it pases in r3 and r4 to the zImage wrapper really are
garbage. However, you're right in that we need to fix the boot wrapper
to not assume all firmwares will follow similar conventions for the entry
path.
Is there a compat property or something similar that could be defined in
the DTS that the wrapper could look at to determine what to expect?
