+Subject: [PATCH] MIPS: lantiq: add support for device tree file from boot
+ loader
+
+This fetches the device tree file like it is specified in the MIPS UHI
+interface if one was found. This is also used when the device tree file
+was appended to the kernel image with cat.
+This code is copied from arch/mips/bmips/setup.c.

+
+Now it is possible to build in no device tree at all and depend on the
+boot loader providing one or someone concatenating a device tree to the
+end of the image.
