ARM: 5903/1: arm/perfevents: add support for ARMv7
Adds the Performance Events support for ARMv7 processor, using the PMNC unit in HW. Supports the following: - Cortex-A8 and Cortex-A9 processors, - dynamic detection of the number of available counters, based on the PMCR value, - runtime detection of the CPU arch (v6 or v7) and model (Cortex-A8 or Cortex-A9) Tested on OMAP3 (Cortex-A8) only.
