It may not make sense, but that is where they are kept currently. It doesn't make sense to maintain 2 copies of a vexpress64.dts device tree in 2 different places...or to maintain 1 lone device tree in u-boot. Maybe we need a git repo for device trees that could be included in Linux, u-boot, and other things a submodule.
