Seem like https://build.opensuse.org/package/view_file/openSUSE:Factory:ARM/JeOS/JeOS-socfpgade0nanosoc.kiwi?expand=1 is missing a <package name="dtb-socfpga" bootinclude="true"/> in the bootstrap packages section ... @ Frank: Can you check booting works also after installing the dtb-socfpga package?
