Add support for building a device tree for sandbox's CONFIG_OF_HOSTFILE option to make it easier to use device tree with sandbox.
This adjusts the Makefile to build a u-boot.dtb file which can be passed to sandbox U-Boot with:
./u-boot -d u-boot.dtb
Signed-off-by: Simon Glass sjg@chromium.org --- Changes in v3: - Add new patch to build a device tree file for sandbox
