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

Hi,

I know, we are in a middle of the merge window, but given that DMA fixes for
NOMMU have landed in Linus tree it'd be handy to have this patch set included
too:

"These MPU patches introduce a nice feature that it simplifies the bootloader:
do not need to setup the MPU, for example for coherent DMA region, which is
described in device-tree too." Andr?s Szemz?

Thanks!
Vladimir

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!

Changelog:

        RFC v2 -> v1
             - dropped RFC tag
	       - Tested-by from Andr?s
	       - rebased on 4.12-rc5

           RFC -> RFC v2
	       - fixed MPU enable for v7m (PATCH 6/7)
