From d438d50848e9425286e5fb0493e0affb5a0b1e1b Mon Sep 17 00:00:00 2001 From: Kyungmin Park Date: Wed, 13 Aug 2008 09:11:02 +0900 Subject: Fix OneNAND build break Since page size field is changed from oobblock to writesize. But OneNAND is not updated. - fix bufferram management at erase operation This patch includes the NAND/OneNAND state filed too.
