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 ? -- Tom
