On a side note, remember that HAS_MMU doesn't mean it's using it - from
what i've read you can use MMU-bearing processors to test uclinux
MMU-less scenarios (dunno if it can be done with every SOC out there,
probably depends on the linux support for each one, at least a couple of
Atmel ones were used this way for testing and/or masochism).
