From 784a90c0a7d8f5aa94b6c7d295ad44ae8e045aa3 Mon Sep 17 00:00:00 2001 From: Sascha Hauer Date: Mon, 7 Nov 2011 12:36:48 +0100 Subject: ARM i.MX: Merge i.MX5 support into mach-imx This patch moves the contents of arch/arm/mach-mx5 to arch/arm/mach-imx and adjusts the Makefile/Kconfig entries in a way that it's possible to compile i.MX5 together with i.MX3/6.
