From c7bf2accc94e081fab0c595c7e5ddd70cfe6b0c1 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Fri, 7 Aug 2015 08:36:16 +0000 Subject: ipq806x: Add ADM support These are cherry-picked & backported from LKML: *https://lkml.org/lkml/2015/3/17/19 They are enabled on both 3.18 and 4.1 kernel. Patches 150 to 154 are applying changes merged since 3.18; they enable mechanisms used by the ADM driver. ADM engine is used by the NAND controller, so it is necessary to bring-up NAND flash support.
