I don't understand. What makes you think I don't want MMC? Both the Plutux
and the Medcom boot from MMC. If you are referring to the CD being
hard-coded, then that is just because I copied from Harmony. You are right
though that I should probably fill the implementation. I'm not really sure
about the best way to do this, though. The struct mmc passed into
board_mmc_getcd() doesn't contain enough information to decide which GPIO to
check. I could assume it is always SD4 since that is the only controller that
is initialized, but would that be acceptable?
