[U-Boot] [RFC PATCH 0/5] 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.

Lokesh Vutla (4):
  arm: v7: Update VBAR only if available
  arm: Kconfig: Add entry for MMU
  arm: v7R: Add support for MPU
  arm: v7R: Add support for enabling caches

Michal Simek (1):
  arm: v7R: Add initial support
