    [POWERPC] Add Makefile rules to wrap dts file in zImage · 916066d5
    Mark A. Greer authored
    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)
