[U-Boot] [PATCH 0/7] arm: Introduce v7R support

[Lokesh Vutla]

The Cortex-R* processors are a mid-range CPUs for use in deeply-embedded,
real-time systems. It implements the ARMv7-R architecture, and includes
Thumb-2 technology for optimum code density and processing throughput.

Except for MPU(Memory Protection Unit) and few CP15 registers, most of the
features are compatible with v7 architecture. This series adds minimal
support for v7-R architecture by reusing the v7 support. Also adding
support for MPU.

Changes since RFC:
- Renamed CPUV7 as CPU_V7A
- Renamed MMU as SYS_ARM_MMU
- Added SYS_ARM_CACHE_CP15
