These headers should be moved to include/linux/platform_data/iommu-omap.h
or something like that. Care to take care of that too?

I guess there's no reason to have both iommu.h and iommuh2.h?

Agree, can this be made as part of a separate cleanup series? I was
hoping these could make it for 3.7 so we could have a usable rpmsg for
omap4.

Omar
