I am about to commit a patch in order to provide Open Firmware
modularization using KOBJ (coincidentally, this should make supporting
FDTs much easier). In order to this, I had to make KOBJ behave itself
when invoked almost at the very beginning of the boot process on both
PowerPC and SPARC, so you shouldn't have any trouble putting this in
very early boot on ARM either once this hits the tree.
