From 77e475cc0ed1832160017d364be32a0be9ff02a9 Mon Sep 17 00:00:00 2001 From: Kyungmin Park Date: Mon, 31 Mar 2008 10:40:36 +0900 Subject: [PATCH] Fix OneNAND read It should access with 16-bit instead of 8-bit Now it uses the generic memcpy with 8-bit access. It means it reads wrong data from OneNAND.
