Fri Nov 25 11:18:05 CET 2011
Add the initial support for Freescale i.MX6Q Armadillo2 board
Support: MMC boot from slot 0/1, debug UART(UART4), usdhc.
There is two MMC slots on the boards:
mmc dev 0 -> connect USDHC3 -> the lower slot on the board,
mmc dev 1 -> connect USDHC4 -> the upper slot on the board,

v3: based on the uart clean up patch:http://patchwork.ozlabs.org/patch/127115/
add CONFIG_MXC_UART_BASE,remove CONFIG_MX6Q_UART4 in board config file
v2:fix sd3 card detection GPIO
remove unneeded parentheses such as (IRAM_SIZE)
remove clean and distclean targets in Makefile
remove CONFIG_MACH_TYPE setup since linux use DT
some cleanup/improvement for the config file from Dirk
remove imx_iomux_v3_init call since assign the base in iomux-v3.c
improve the commit message to add the mmc slot description
