Well, yes you're right although when I think about it, it's been like that (for
both 64 and 32) since the introduction of CONFIG_MPU by commit (in October last
year):
0388a5979b21 ("xen/arm: mpu: Introduce choice between MMU and MPU")
If you're saying that all the Kconfig combinations + targets like allyes/allno
need to build successfully also for new ports (MPU on Arm is kind of like a new
port), then I agree (I did not think about it and clearly others too seeing the
MPU patch above) although I'd prefer to avoid sending a patch adding dependency
just to be removed in 1-2 weeks. But I can do whatever you think needs to be
done.
