Surely possible.
As you known, there is no interface for selecting device.
Can I add new command for that? (E.g. mmcselect <device num>)

And I want to change the mmcinit command too.
I.e. getting dev num by argument.
like this

mmcinit <device num>

If that is not in, we must select mmc device before mmcinit.
How about this? There exist any side effects?

Thanks :)
