The SysTick is a 24-bit down counter that is found on all ARM Cortex M3, M4, M7 devices and is always located at a fixed address. The number of reference clock ticks that correspond to 10ms is normally defined in the SysTick Calibration register's TENMS field. However, on some devices this is wrong, so this driver allows the clock rate to be defined using CONFIG_SYS_HZ_CLOCK.
