From 970f3959d39708f3da3e5c181e645c1f9a010628 Mon Sep 17 00:00:00 2001 From: Bruce Ashfield Date: Wed, 9 Feb 2011 00:45:23 -0500 Subject: linux: factor dts/dtc/dtb handling into a specific include Fixes [BUGID #610] The powerpc linux-yocto kernels were not creating dtb images in the deploy directories. This was due to two problems: - the dtb generation rules were not being configured - the boards were not specifying a device tree in their config This change addresses the first point by factoring out the dtb generation routines into a new include that can be used by multiple recipes.
