ok I got this working by using the u-boot.bin $ make u-boot.bin and put it into the imx-mkimage repo from here: https://source.codeaurora.org/external/imx/imx-mkimage to create the full bootstream with scfw + atf + u-boot. I thought that I could create the full bootsteam directly in u-boot repo with: > $ make flash.bin as seen for other imx8 boards. Perhaps that is possible too but I don't got it working that way.
