From ab0689c316c9b2ee33f4de1c50263b64e539f12a Mon Sep 17 00:00:00 2001 From: Kyungmin Park Date: Wed, 26 Nov 2008 10:18:13 +0900 Subject: [PATCH] Move machine specific code to board at s3c64xx (v2) Move machine specific code to smdk6400. Some board use OneNAND instead of NAND. Some register MP0_CS_CFG[5:0] are controled by both h/w and s/w. So it's better to use macro instead of hard-coded value.
