Most architectures use jump_to_image_no_args() to jump from SPL to U-Boot. At present sandbox is special in that it jumps in its spl_board_load_image() call. This is not strictly correct, and means that sandbox misses out some parts of board_init_r(), just as calling bloblist_finish(), for example.
Change spl_board_load_image() to just identify the filename to boot, and implement jump_to_image_no_args() to actually jump to it.
