From e445d2c690c34300306a197f4c8aebcae87bb728 Mon Sep 17 00:00:00 2001 From: Shawn Guo Date: Tue, 13 Aug 2013 13:54:02 +0800 Subject: [PATCH 31/59] ARM: imx: add soc revision helper functions Similar to what we do for cpu type, the patch adds helper functions imx_set_soc_revision() and imx_get_soc_revision() to maintain imx_soc_revision in cpu.c.
