    ARM: omap3: beagle: Enable DM_SERIAL, update distro usage and NAND layout

broke MMC access on Beagleboard xM (rev. B). For my SD card with 2 partitions, I get the following errors:
* 'ls mmc 0:1' returns: ** Unrecognized filesystem type **
* 'ls mmc 0:2' returns: ** Invalid partition 2 **


Not sure which part of this patch cause this bug.
