Ah, now I follow.  That is worth considering.  That would make some 
assumptions too, just different ones.

Of the top of my head...
* All CPUs are clocked the same (unlikely to be a problem)
* That the CPU actually _needs_ the fixups (currently they all get the 
fixup so it isn't currently a problem)

As long as it works for the bootwrapper, it would work for u-boot.  The 
two are imperfect subsets of each other, however.
