Currently all rk3188 based devices including radxa rock uses the same bootloader from Rockchip. Rockchip don't provide the source code of the bootloader. The bootloader's main task is:
- Load and boot the kernel.img/boot.img or recovery.img from correspoding partition
- Communicate with the host PC to download the image/firmware for upgrading
