It uses the same API as 8435ae76eSBin Meng lib/time.c, but now implemented by the uclass. The first timer 9c8a7ba9eSThomas Chou will be used. The timer is usually a 32 bits free-running up 10c8a7ba9eSThomas Chou counter. There may be no real tick, and no timer interrupt. 11c8a7ba9eSThomas Chou 12e9e5d9d2SPhilipp Tomsichconfig SPL_TIMER 13e9e5d9d2SPhilipp Tomsich bool "Enable driver model for timer drivers in SPL" 14e9e5d9d2SPhilipp Tomsich depends on TIMER && SPL 15e9e5d9d2SPhilipp Tomsich help 16e9e5d9d2SPhilipp Tomsich Enable support for timer drivers in SPL.
