From 8dfafdde88eb3e71d5569846396ae67a91017232 Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Fri, 4 Oct 2013 10:22:41 -0500 Subject: Introduce common timer functions Many platforms duplicate pretty much the same timer code yet they all have a 32-bit freerunning counter register. Create a common implementation that minimally requires 2 or 3 defines to add timer support: CONFIG_SYS_TIMER_RATE - Clock rate of the timer counter CONFIG_SYS_TIMER_COUNTER - Address of 32-bit counter CONFIG_SYS_TIMER_COUNTS_DOWN - Define if counter counts down All functions are weak or ifdef'ed so they can still be overriden by any platform.
