From 9653921eadd5d5268afbee6c928708158fc4e844 Mon Sep 17 00:00:00 2001
From: Josua Mayer <josua.mayer97@gmail.com>
Date: Tue, 22 Nov 2016 16:33:23 +0100
Subject: [PATCH 3/4] clearfog: enable distro boot code
load addresses start at 0x02000000, leaving enough space for fdt,
boot scripts and ramdisk at the end.
Only boot from mmc, the other options are not in working order.
Removed *_high variables in good faith. They can be re-added with sane
values when, and if required.
