From 226045734189690e91b7a101d22ce94793209bab Mon Sep 17 00:00:00 2001 From: Sanchayan Maity <maitysanchayan@gmail.com> Date: Mon, 24 Nov 2014 11:03:59 +0530 Subject: [PATCH] mtd/nand/vf610_nfc: Disable subpage writes This patch disables subpage writes for vf610_nfc nand driver. This is required, as without this fix, writing unaligned u-boot images with DFU results in a hang. Trying to write unalgined binary images also results in a hang, without disabling subpage writes. Patch has been tested on a Colibri VF61 module.
