From 58c90c88ad6b7df8fdc986bd0a6a54da0048a318 Mon Sep 17 00:00:00 2001 From: Holger Brunck Date: Fri, 15 Aug 2014 10:51:48 +0200 Subject: [PATCH] arm/km: disable subpage write for km_kirkwood_pci and kmsuv31 target Newer FLASH types used on these boards don't allow writing of subpages. So disable subpage write in the NAND driver. Additionally we need to tell the UBI layer in the kernel that he also should only write 2048 bytes. This is done with an additional command line parameter for the kernel commandline.
