I am not saying gpt image. What i mean is the single boot.img which contain
kernel zimage, device tree and extlinux file. with this file, i can use
below command update kernel and device tree. There are many people prefer

upgrade_tool db RK3288UbootLoader_V2.30.06.bin
upgrade_tool wl 32768 deploy/images/firefly-rk3288/boot.img
