Overall looks pretty good, let's wait for a few more Acks or a possible
Nak and then put it into arm-soc. You can add my 'Acked-by' to all patches
if you like.

Just curious: do you have more information on this? Are all i.MX31 ARMv6
and all i.MX35 v6k as the current Kconfig claims, or is it more
complicated?

Makes sense. It's still a cleanup, so you could send it as a
separate patch to be applied on-top of the pull rather than the
same pull request, although the difference is really marginal.
You are probably right in leaving out the non-multiplatform
platforms, but maybe we can figure out whether they should be
changed as well, especially as some of them are going to become
multiplatform-enabled in the future:
* ARCH_S5P64X0 should be changed, it's next on the list
* DaVinci/TNETV107X looks rather broken, I wonder if we should
just remove it entirely rather than fix it. I have a series
to fix all 'randconfig' build bugs locally and there were a
lot of them for TNETV107X, and I doubt fixing the build will
actually give you a booting kernel.
* ARCH_MSM7X00A should just be changed, although probably nobody
really cares.
* integrator and realview apparently allow both CPU_V6 and CPU_V6K
to be manually selected. Is that actually the correct behavior
in that both kinds of core tiles exist?
