[PATCH 2/5] bootwrapper: Add CONFIG_DEVICE_TREE
From: Scott Wood <hidden>

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 desired.
