The current da850evm config is missing the pieces for NAND support that can be found in the u-boot-davinci tree [1].
This patch adds NAND support in the spirit of the support in the u-boot-davinci tree where NAND support for the da850evm can be enabled by putting a single '#define CONFIG_USE_NAND' at the top of the include/configs/da850evm.h file.
