From 3995eb82050a81e11217a0b88b2a5eddd53eb4d6 Mon Sep 17 00:00:00 2001 From: Shawn Guo Date: Thu, 13 Sep 2012 19:48:07 +0800 Subject: ARM: imx: merge plat-mxc into mach-imx It's really unnecessary to have plat-mxc, and let's merge it into mach-imx. It's pretty much just a bunch of file renaming and Kconfig/Makefile merge. To make the change less invasive, we keep using Kconfig symbol CONFIG_ARCH_MXC for mach-imx sub-architecture.

The files in mach-imx/devices will need to include "../hardware.h".
