[U-Boot] [PATCH v8 01/14] sandbox: Build a device tree file for sandbox

Mon Feb 17 23:06:35 CET 2014
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
