- * This code reads directly from an ARMv7 memory-mapped timer that lives in
- * MMIO space. Since this counter lives inside of MMIO space its shared between
- * cores and that means we don't have to worry about issues like TSC on x86
- * where each time-stamp-counter (TSC) is local to a particular core.

- * Register-level access code is based on
- * drivers/clocksource/arm_arch_timer.c
