Subject: ARM: mpu: Ensure that MPU depends on CPU_V7
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=de8297765def67ec40b69522f3e405a61e0217b3;p=deliverable%2Flinux.git

ARM: mpu: Ensure that MPU depends on CPU_V7

The support for the MPU is currently implemented only for R-class
(PMSAv7/R). Since the merge of V7M support in to the kernel it is possible
to select MPU support on V7M.

This patch ensures that until MPU support for M-class processors is
implemented, the MPU can only be selected with R-class CPUs
