[PATCH 3/7] arm: mach-omap: Change mountpoint of boot partitions

[Daniel Schultz]

If using EMMC and SD as bootsources, mounting the boot partition of both
devices to /boot makes trouble. Either the correct device is mounted to
/boot or a remount of /boot has to be performed.

To ensure this problem each MMCn bootsource will be mounted to his own
path in /mnt/{mmc,emmc}.
