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.

The nand controller in IPQ806x is of the 'EBI2 type'. Use the corresponding
|

compatible string.
