From c97088c3cfa84e7e53fddd26896f145cc8c431a2 Mon Sep 17 00:00:00 2001 From: Francois Retief Date: Wed, 28 Oct 2015 15:18:22 +0200 Subject: sparc: Update cpu_init.c to use generic timer infrastructure Introduce the CONFIG_SYS_TIMER_* macros in include/asm/config.h to make use of the generic timer infrastructure in lib/time.c. Created a timer_init() function to initialize the timer hardware and update the #ifdef in board_init_f to allow this function to be called during the start-up sequence.
