An interesting question. u-boot itself is always running of mmc 0, or loaded through FEL, but that does not mean that e.g. extlinux.conf + the kernel and dts could not be on mmc 1. So yes I guess we do want to add mmc 1 as boot target. First lets get Chen's patches + my existing second mmc slot set merged into u-boot-sunxi next, and then I'll do a patch on top of that.
