Card detect / WP handling for MMC2. If your following patches will cover that, it will be great!

There are no public schematics yet, though. > Do VMMC1 and GPIO-0/CD hook up to MMC1? > Do VMMC2 and GPIO-1/CD hook up to MMC2? Yes. There are also WP GPIOs connected from OMAP3 to both slots. >> Another way is to just copy mmc-twl4030.c >> and add stuff there, but that would result in lots of code >> duplication.
