I don't know, I've not looked at the remainder of the patches.  Having
looked briefly at them, it looks like they touch EFM32 as well, so I'm
not sure having them all go through iMX is the right approach either.

Looking at the EFM32 patch, it looks like we've adopted my suggestion
(discussed with Arnd in the previous month) wrt noMMU, so I'll post a
couple of patches in a moment which fix Integrator for this as well.
Integrator is independent of this series, and it fixes real problems
caused by the single zImage stuff for noMMU there.

It makes sense for these to all go through arm-soc - but the question
is how do we get them all into arm-soc...
