From: Sukumar Ghorai Date: Fri, 28 Jan 2011 10:12:03 +0000 (+0530) Subject: omap3630: nand: fix device size to work in polled mode X-Git-Tag: MMI-PSA29.97-13-9~20087^2~28^5~10 X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d5ce2b65;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git omap3630: nand: fix device size to work in polled mode zoom3 and 3630-sdp having the x16 nand device. This patch configure gpmc as x16 and select the currect function in driver for polled mode (without prefetch enable) transfer.
