The i.MX 6UL/ULL feature a Cortex-A7 CPU which suppor the ARM generic timer. This change makes use of the ARM generic timer in U-Boot. This is crucial to make the ARM generic timers usable in Linux since timer_init() initalizes the system counter module, which is necessary to use the generic timers CP15 registers.
