Is your feature request related to a problem? Please describe. During development we need to analyze behavior of system using PMU device included in the ARM Cortex A architecture.

Describe the solution you'd like Add interfaces providing the following

  1. Initialization of PMU unit
  2. Start of PMU counters
  3. Stop of PMU counters
  4. Print of PMU counters

So, designers may invoke start, stop and print PMU counters in various parts of application code and estimate behavior.
