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. So,reuse the same armv7 folder and introduce a new config CPU_V7R in order to differentiate from v7 based platforms.
