[U-Boot] [PATCH][v2] arm: imx: imx-common: init: move arch init common setup
Move common imx6 arch init setup, init.c can be extended and reused to support imx7 SoC keeping init arch common code.
Signed-off-by: Adrian Alonso aalonso@freescale.com --- Changes for V2: Move back mx6 ldo related to functions into soc.c Apply patch on top of: arm: imx: common rework cache settings for imx6
