[POWERPC] Add Makefile rules to wrap dts file in zImage
Add 'zImage.dts' and 'zImage.dts_initrd' build rules that automatically compile and wrap a dts file from arch/powerpc/boot/dts into the zImage file. The resulting zImage will be arch/powerpc/boot/zImage.dts.<platform> and arch/powerpc/boot/zImage.dts_initrd.<platform>, respectively. Having separate rules allows the user to choose whether to include a device tree--and which device tree--at build time. This is useful when one Makefile target builds a zImage that runs on several platforms except for differing device trees. By just setting CONFIG_DEVICE_TREE and running "make zImage.dts" the exact zImage you want is built without Makefile bloat or manually running the wrapper script. The dts file is expected to be arch/powerpc/boot/dts/$(CONFIG_DEVICE_TREE) Signed-off-by: Mark A. Greer <mgreer@mvista.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
