[RFC PATCH 0/7] ARM: NOMMU: MPU updates

[Vladimir Murzin]

Hi,

This is an update of the existent MPU code which consist set of
clean-ups and enhancements. The most significant changes are in the way
how MPU settings sync-up for secondaries (PATCH 3/7) and more flexible
layout for memory (PATCH 7/7). Since there is no in-tree user of MPU,
support for M-class has been added (PATCH 6/7).

Thanks!

  ARM: NOMMU: Update MPU accessors to use cp15 helpers

  ARM: NOMMU: Disallow MPU for XIP
  ARM: Kconfig: Kill CONFIG_VECTORS_BASE
  ARM: V7M: Add support for MPU to M-class
