Upstream ARM Trusted Firmware support Rockchip SoCs:
Build ATF
Here is a mk-atf.sh script to build ATF.
$ cat mk-atf.sh #!/bin/bash make realclean CFLAGS='-gdwarf-2' \ CROSS_COMPILE=aarch64-linux-gnu- \ make PLAT=rk3399 DEBUG=1 ERROR_DEPRECATED=1 bl31
Because there is a blob of code for cortex-M0, so you need a compiler for it. Install it by:
sudo apt-get install gcc-arm-none-eabi
We can get bl31.bin when build complete.
Install ATF
Support ATF with SPL FIT image[edit]
Using Rockchip miniloader[edit]
Alternatively, you can use Rockchip miniloader and U-Boot instead which do not need SPL.
The miniloader is package as IDBlock, and the u-boot.bin need to package with rockchip tool:
loaderimage --pack --uboot u-boot.bin rk3288_uboot.img
According to the partitions definition, this output should write to offset 0x4000.
