Typically "fatinfo mmc 0". The command is of the format "fatinfo <interface>
<dev[:part]>"
Interface is important for common/cmd_fat.c function get_dev() where it
calls a different function for each name. It passes the device number to a
function mmc_get_dev which is probably in your cpu-specific files unless
something has changed since 1.1.5. My at91 mmc/sd implementation is quite
simple because I only support one device. I completely ignore the dev
parameter and return a pointer for the only device available on my system.
