[PATCH 1/13] powerpc: Add Makefile rule to wrap dts file in zImage
From: Mark A. Greer <hidden>
Date: 2007-04-25 23:55:04
Add 'zImage.dts' and 'zImage.dts_initrd' build rules that automatically compile and wrap a dts file into the zImage file. The rules are similar to the initrd rules. The dts file is expected to be arch/powerpc/boot/dts/$(CONFIG_DEVICE_TREE) Signed-off-by: Mark A.
