    [POWERPC] bootwrapper: Add CONFIG_DEVICE_TREE
    This provides a way to tell the bootwrapper makefile which device tree to
    include by default.  The wrapper can still be invoked standalone to wrap
    with a different device tree without reconfiguring the kernel, if that is
    The user will only be asked to provide a device tree if the platform
