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.
