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
#: name size offset

-------------------------------------------------
- Use MMC and UBIFS support from config_distro_bootcmd.h
- Use LEGACY_MMC and NAND support defined in omap3_beagle.h
[MMC(0:1)/extlinux/extlinux.conf]

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.
