I would not use "depends on ARCH_MULTI_V7 || ARCH_MULTI_V7R" for
a machine that actually has an ARMv7-A core, that would be a bit
confusing.

If we want to allow building a kernel for ARMv7-A with MMU disabled,
I'd drop the 'depends on MMU' for ARCH_MULTI_V7 and move it to
whatever parts of the kernel actually have a build-time dependency
or that are known to be broken in that configuration.
