The BootROM of the RK3399 SoC does not initialise the cntfrq_el0 (which holds the value 0 (zero) on entry into the SPL. This causes the timebase for U-Boot not to advance (and will cause a hang where a timeout would be expected... e.g. if something goes wrong during MMC/SD card startup). This change defines COUNTER_FREQUENCY, which is used by the AArch64 init code in arch/arm/cpu/armv8/start.S to set up cntfrq_el0 (if necessary).
