From 6b2c6468952749ec3a9acc5cd9ee4bc4e7a5a59b Mon Sep 17 00:00:00 2001 From: Ben Gardiner Date: Thu, 14 Oct 2010 17:26:25 -0400 Subject: da850evm: setup NAND support under CONFIG_USE_NAND The current da850evm config is missing the pieces for NAND support that can be found in Sandeep's 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.
