There's some whitespace issues that I'm sure you'll fix for the next
version.  One naming thing that I think needs a little work is that we
say CONFIG_ARM_MPU (which is OK'ish, can we use something a little more
specific?  It's a V7 architectural thing, yes?) but then v7m_mpu.h, even
tho we use it on both v7r and v7m as there's just a few differences.
That should get consolidated, off the top of my head, to
CONFIG_CPU_V7_HAS_MPU (following other things like virt) and maybe
v7_mpu.h ?
