[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=920b50b7e0d7535899ccba77b85d3df57e2c2a2a
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Allow to generate u-boot-dtb.img. This is the same format
as u-boot.img, however, it contains a built-in device-tree.
This file is being loaded by the U-Boot SPL.
