Wrong. We already have that working with mainline plus some additional
patches. OMAP people want it, and it's precisely the direction which
quite a number of people within the ARM community want to move.

Building an ARM kernel to cover multiple different CPU types is something
which has always been possible, although with SMP and a few other things
it's become a little harder. Not impossible though, and not impossible
to do efficiently either.
