None of the stuff you have applied is included in the objects compiled
for Versatile boards. The PL022 driver probably works with Versatile
but noone has tested it and it's not included in any defconfigs.

What I though Russell was worried about was the PL011 and PL180
drivers which *are* in use by Versatile.

So to be clear: none of the stuff that touches the Versatile platform
has been applied so far. Only the U300/U8500 specific stuff has
been patched in, and I'm suggesting also the PL022 driver which
is currently only used by U300 and U8500 to be patched.

That said I hope to bring in help, run QEMU or similar ASAP
so that also the PL011 and PL180 can be cleanly applied for
2.6.35...
