This patch adds the NAND support on OMAP3EVM board and also allocates five partitions on NAND.

You don't need this include.

Missing comma. Have you at least tried compiling this? [Hrishikesh] Apologies. I maintain different git repositories .Had compiled and tested in other one , missed out the commas while making changes in this one. Will send out a patch with perfect changes in my next revision.
