Bug Description

in lucid we had /dev/mtdblock devices on omap3, we need these if NAND exists on the HW to modify the bootloader defaults from userspace, please enable NAND support again in maverick.

The driver is compiled in but the flash start address is not properly set. Initialization of mtd device changed between Lucid and Maverick. Base address seems to have been left out.

The problem came from the gpmc not being initialized before accessing the nand flash. Gpmc and the nand flash driver were decoupled after Lucid and the change was not reflected in "omap3beagle_flash_init".
