[PATCH v2 0/4] Introduce PMSAv8 memory protection unit

[Vladimir Murzin]

Hi,

This series adds support for PMSAv8 MPU defined by ARMv8R/M
architecture.

Changelog:

     v1 -> v2
        - Included missed patch.
	- Folded "ARM: NOMMU: Make _stext and _end meet PMSAv8 alignment
	  restrictions" into "ARM: NOMMU: Support PMSAv8 MPU" since it
	  allows us to refer PMSAv8_MINALIGN in linker scripts.
	- Improved and tested XIP support

    RFC -> v1
        - Rebased on v4.16-rc1
	- Added Tested-by for v7M bits from Andras

Thanks!
