I'am using the u-boot master branch with my board patches. Together with
the M4 Image. This particular problem is solved now by adding the right
reserved-memory statement and linux,cma {} statement.
No more kernel crashes yet. Now the kernel starts systemd and is stucked
there. I get no login prompt. It looks for me like getty can't find any
serial to attach. But the kernel is still running and writing to serial
lpuart32.
Best regards,
Oliver

You can use https://webchat.freenode.net/ if you don't have an IRC client handy.

So after some more digging I assume that this error is related to a missing "reserved-memory" node in my devicetree. Now I need to find out how to split up my memory the right way for this imx8qm congatec board. Any hints?
