RK3399 platform has two stage boot loaders like SPL and U-Boot proper. For each stage we need to burn the image on to flash with respective offsets. This patch create a single image using binman, so that user can get rid of burning different stage boot images. without this patch: ------------------ ₹ sudo dd if=spl/u-boot-spl-rockchip.bin of=/dev/sdc seek=64 ₹ sudo dd if=u-boot.itb of=/dev/sdc seek=16384 with this patch: --------------- ₹ sudo dd if=u-boot-rockchip-with-spl.bin of=/dev/sdc seek=64 This would easily extend if other rockchip family SoC's would make use of single image creation.
