Ah, no, things have bad names perhaps.  CMD_USB_MASS_STORAGE enables
"ums" as a command which is what in turn will export MMC (or something

I think it's a useful command that should be more widely exposed, yes.
IIRC, it's how the Tegra platforms support flashing their dev boards
with official images, and can be a handy "rescue" type option too.

OK, thanks.  I just might since I really want to move on to grabbing
some fs patches and before I do that I really want to have as much
testing of them as possible.
