I've carried an experimental patch to enable !MMU in combination with
MULTIPLATFORM for a while, it's probably time to do this for real now,
especially since we now have two !MMU platforms that can be built
together. Independent of the question of whether such a combined kernel
could run on real hardware or anybody would want to run such a kernel
if it were possible, I think it's very useful to be able to build
allmodconfig with MMU disabled and get all drivers for the available
platforms for build testing.
