Currently, "mmc dev 0" does not change the selected HW partition. I think it makes more sense if "mmc dev 0" is an alias for "mmc dev 0 0", i.e. that HW partition 0 (main data area) is always selected by default if the user didn't request a specific partition. Otherwise, the following happens, which feels wrong:
Select HW partition 1 (boot0): mmc dev 0 1
Doesn't change the HW partition, so it's still 1 (boot0): mmc dev 0
With this patch, the second command above re-selects the main data area.
Note that some MMC devices (i.e. SD cards) don't support HW partitions. However, this patch still works, since mmc_start_init() sets the current partition number to 0, and mmc_select_hwpart() succeeds if the requested partition is already selected.
Pantelis, does this series look good?
