[U-Boot] [PATCHv2 4/6] omap3evm: Add (quick) configuration for MMC/SD only

[Sanjeev Premi]

Add an optimized board configuration that only
supports boot from MMC/SD.

Signed-off-by: Sanjeev Premi <premi at ti.com>

 Changes in v2:
   Use rootfstype=ext3 (as in the default config) to allow
   existing partitions to be used as-is.
