From 272f548fe8d0b811e0589e535f650f0507f6bccd Mon Sep 17 00:00:00 2001 From: Owen Kirby <osk@exegin.com> Date: Fri, 11 Apr 2014 17:59:55 -0700 Subject: [PATCH 2/3] [at91] AT91SAM9G20-EK fixes. While testing the 3.10 kernel update, I found that the out-of-the-box device tree for the the AT91SAM9G20EK uses a UBIFS rootfs and stores the DTB separately from the zImage.
