From d6d0597cdf2f8fc7ba305a920c20a7fb912d8401 Mon Sep 17 00:00:00 2001 From: John Crispin Date: Sun, 20 Mar 2016 14:41:54 +0000 Subject: lantiq: use upstream mechanism to append device tree file Instead of using our patch-dtb program just place the device tree behind the kernel binary and then let the in kernel mechanism fetch it. This also adds support for having the device tree file in the boot loader.
