Here is a stab at adding SPL NAND support for i.MX6. I tried to take into account comments from previous attempts by others but there is still some work to be done and in particular I need some help with the issue of dealing with IMX6Q vs IMX6DL iomux in a way where the current defines can be shared by SPL as well as imximage.
Some of these can be split out of the series if needed but I wanted to post them originally as a series to provide full context. The resulting SPL+u-boot.img has been tested on 4 different Ventana baseboards with a variety of CPU and DDR3 options.
