Darwin Rambo	de351d6be6	lib: time: add weak timer_init() function If timer_init() is made a weak stub function, then it allows us to remove several empty timer_init functions for those boards that already have a timer initialized when u-boot starts. Architectures that use the timer framework may also remove the need for timer.c.

lib: time: add weak timer_init() function

If timer_init() is made a weak stub function, then it allows us to
remove several empty timer_init functions for those boards that
already have a timer initialized when u-boot starts. Architectures
that use the timer framework may also remove the need for timer.c.

driver to conform to this.
