This commit does the following for BeagleBoard{-xM}:
- Enable DM_SERIAL which also enables SPL_DM_SERIAL - Misc. config updates in support of DM_SERIAL - Use updated NAND layout (BeagleBoard):
device nand0 <omap2-nand.0>, # parts = 6

- Use MMC and UBIFS support from config_distro_bootcmd.h - Use LEGACY_MMC and NAND support defined in omap3_beagle.h

The board's 'bootcmd' can also be overridden with:
CONFIG_BOOTCOMMAND="run findfdt; run mmcboot" CONFIG_BOOTCOMMAND="run findfdt; run nandboot" CONFIG_BOOTCOMMAND="run findfdt; run ramboot"
or
CONFIG_BOOTCOMMAND="run findfdt; run somethingelse"
The use of 'run findfdt' is required.
