Hi! Embedded devices often use multiple SD/MMC devices as boot/rootfs disks. Some of them are removable, some not. If the removable cards are not present, but are probed before the non-removable ones, the indexing scheme changes. This makes it harder to hard-code the rootfs in the cmdline. First solution I came up with was the alias-node in DT. I guess my implementation is pretty hacky and ugly, but you can get lost pretty fast in the whole mmc stack. For example, the second patch should use "card->host->index" instead of parsing the alias again, I guess. I'm not sure why it currently doesn't though. So, if there is a better place or solution to specify a reliable ordering of mmc devices, please let me hear it.
