[ARM PATCH] 1955/3: Motorola i.MX architecture support
Patch from Sascha Hauer
This patch adds support for the Motorola i.MX SoC. It has board
support included for the MX1ADS Eval Board, but the patch has been
tested on two other custom boards as well.
Things changed since Patch 1955/2:
- fixed according to Russell's comments.
- removed unnecassary files from include/asm-arm/arch-imx.
- removed cpufreq support (it needs rework).
- made myself the Maintainer of mx1ads
