All rockchip platforms support TPL or SPL-based bootloader in mainline with U-Boot proper as final stage. For each stage we need to burn the image on to flash with respective offsets.
This patch creates a single boot image component using - binman, for arm32 rockchip platforms - pad_cat, for arm64 rockchip platforms.
This would help users to get rid of burning different boot stage images.
The new image called 'u-boot-rockchip.bin' which can burn into flash like:
₹ sudo dd if=u-boot-rockchip.bin of=/dev/sda seek=64
This would support all rockchip platforms, except rk3128 since it doesn't support for SPL yet.
