Could you confirm whether U-Boot 2021.07 boots for you?

Harald and I found the problem: it is related to ATF.

These extra patches were missing in our ATF build: https://github.com/compulab-yokneam/meta-bsp-imx8mm/tree/iot-gate-imx8-dev/r...

After applying them, the board boots fine with mainline U-Boot.

I will send a patch documenting the procedure to make it easier for other users.

Thanks,
