From 7fafb06831431ed7bc882c3cd7c981e3f41cfdb0 Mon Sep 17 00:00:00 2001 From: Andrew Bresticker Date: Thu, 21 Aug 2014 13:04:20 -0700 Subject: MIPS: Create common infrastructure for building built-in device-trees In preparation for moving the device-trees to a common location, introduce the config option BUILTIN_DTB, which can be selected by platforms that use a device-tree built into the kernel image, and create a Makefile to build the device-trees in arch/mips/boot/dts/.
