From d523866eb39d8957fa16e05ebabf04101bfb5f85 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Fri, 7 Aug 2015 08:36:31 +0000 Subject: ipq806x: add NAND flash controller support These patches add support for ipq806x NAND flash controller. Most of these are cherry-picked & backported from LKML: *https://lkml.org/lkml/2015/8/3/16 This patch just modifies the kernel code, but doesn't change the config. It should be harmless.
