[RFC PATCH 0/5] Introduce PMSAv8 memory protection unit

[Vladimir Murzin]

Hi,

This series is an attempt to add support for PMSAv8 MPU defined by
ARMv8R/M architecture.

I'm have a doubt about adding dedicated config option, so both v7 and
v8 versions of PMSA are covered with CONFIG_MPU, but I'd glad to hear
what people think of it.

Thanks!

Vladimir Murzin (5):
  ARM: NOMMU: Move PMSAv7 MPU under it's own namespace
  ARM: NOMMU: Reorganise __setup_mpu
  ARM: NOMMU: Postpone MPU activation till __after_proc_init
  ARM: NOMMU: Make _stext and _end meet PMSAv8 alignment restrictions
  ARM: NOMMU: Support PMSAv8 MPU
