From ecb7be2985e130d1d3f7569f086cf50bfe60d337 Mon Sep 17 00:00:00 2001 From: Lauri Hintsala Date: Tue, 17 Apr 2012 00:35:46 +0000 Subject: [PATCH] mx28evk: add NAND support NAND support is not enabled by default because Eval Kit is not delivered with NAND chip. To enable NAND support add CONFIG_CMD_NAND to board config.
