From cd20f2afe2da42a98a4071dedb86590f0d53bd21 Mon Sep 17 00:00:00 2001 From: Peng Fan Date: Wed, 22 Feb 2017 16:21:43 +0800 Subject: imx: mx7ulp: Add soc level initialization codes and functions Implement soc level functions to get cpu rev, reset cause, enable cache, etc. We will disable the wdog and init clocks in s_init at very early u-boot phase. Since the we are seeking the way to get chip id for mx7ulp, the get_cpu_rev is hard coded to a fixed value. This may change in future. Reuse some code in imx-common.
