I'm fully aware of that ;-)

Unfortunately it's not trivial.
How do you enforce that at least one option from a list of options is enabled?

M68k (with MMU) supports three distinct classes of machines:
1. Coldfire (with Coldfire MMU)
2. Sun-3 (with Sun-3 MMU)
3. Rest (with classic Motorola MMU)

Class 3 contains multiple machine types (cfr. top of arch/m68k/Kconfig.machine)
and at least one of them must be selected.
So far everything I tried conflicted with enforcing the 3 distinct classes.

For nommu, it's simpler, as you can typically support a single platform only,
due to the different platforms (usually) having RAM at different addresses.

Suggestions are welcome....
