With this change, U-Boot behaves as follows: - Begin with no SD card inserted in "mmc 1" - Execute: mmc dev 1 - This fails, since there is no card - User plugs in an SD card - Execute: mmc dev 1 - The newly present SD card is detected I know that "mmc rescan" will force the HW to be reprobed, but I feel it makes more sense if "mmc dev" always reprobes the HW after selecting the current MMC device. This allows scripts to just execute "mmc dev", and not have to also execute "mmc rescan" to check for media presense.
