As usual, I find it basically impossible to read your wall of text. I did notice that paragraph while trying to skim through it. If you want to select an MMC device regardless of what USB devices may be present, set loaderdev to mmc, mmc0, mmc1, etc. If there are multiple mmc devices which may or may not be present, there's not much you can do, because if no card is present in the slot uboot normally assigns to mmc0, then any card in the other slot will become mmc0. The same applies to other device types such as sata and usb, you can name the type, but uboot will always just number whatever is present starting at 0 without regard to the physical slot/port/location/whatever. -- Ian
