The ARM Linux kernel requires the DT to be in memory accessible early during the boot process. This always happens naturally on the RPi 1, since the maximum memory size of 512MiB, and additionally some of that is reserved for use by the GPU. The RPi 2 has 1GiB of RAM (minus some GPU usage), and so if the DT is relocated to the top of RAM, Linux cannot access it. Prevent this from happening by setting fdt_high.
