From 3fd38af704f6d4da50fe7dbf9ff018e43b196fb4 Mon Sep 17 00:00:00 2001 From: Kevin Smith <kevin.smith@elecsyscorp.com> Date: Mon, 18 May 2015 16:09:46 +0000 Subject: [PATCH] db-88f6820-gp.h: Load data blobs into lower memory By default on this platform, u-boot loads data into high memory in the range of 0x7Fxxxxxx, which generates a data abort when the kernel tries to read it. Config the u-boot environment to load the device tree and initrd image into lower memory to make them accessible to the kernel.
