Add some boilerplate, Makefiles, Kbuild. A generic barebox-dt-2nd.img image can be build for A64 SoC using the sunxi_v8_defconfig. This image can be booted from u-boot and has been tested on Pine64+, it should work on other A64 SoC such as the pinephone, and other Pine64 boards, it might also work on H6 SoC which uses the same sd/mmc controler.
