I like the sound of this ;-)

To get you started I just sent out two other patches you can consider
as RFC, they're regrettably not even compile-tested. I mainly wanted
to indicate what needs to be done so we can throw them away, just
wanted to give a hint.

Well I guess if there is nobody testing it, then nobody cares.
The world must be full of people with PXA platforms doing nothing
but regression testing...

Actually just days ago I asked Haoijan to help me testing a set of
patches for the PXA SPI controller, and he kindly helped out, so there
are some people booting these platforms, sometimes :-)
