From b8ed8d1969d530746cc5c9c4d45cb150033b9bd4 Mon Sep 17 00:00:00 2001 From: Huang Shijie Date: Mon, 9 Jan 2012 15:59:01 +0800 Subject: [PATCH] ENGR00169906-2 GPMI : setup the TIMING1 for ready/busy The TIMING1 specifies the timeouts used when monitoring the NAND READY pin and IOWAIT signals. We should set a default value for it.
