+From 5701384cea4a829b772bf7a96a74825b58c22385 Mon Sep 17 00:00:00 2001
+From: Denys Dmytriyenko <denys@ti.com>
+Date: Thu, 17 Apr 2014 12:25:40 -0400
+Subject: [PATCH] am335x_evm.h: Add, use DEFAULT_LINUX_BOOT_ENV environment
+ string
+
+Modified version of the patch currently being reviewed for mainline:
+http://patchwork.ozlabs.org/patch/334861/
+
+To deal with a reoccurring problem properly we need to specify addresses
+for the Linux kernel, Flatted Device Tree and ramdisk that obey the
+constraints within the kernel's Documentation/arm/Booting file but also
+make sure that we relocate things within a valid address range.
