From e6a07569611daf4190c0fd2c2bb1e2189c0cb479 Mon Sep 17 00:00:00 2001 From: Shawn Guo Date: Mon, 8 Jul 2013 21:45:20 +0800 Subject: ARM: imx: let L2 initialization be a common function Move imx6q L2 initialization function imx6q_init_l2cache() into system.c, and rename it imx_init_l2cache(), so that other platforms other than imx6q can also use the function.
