Please don't forget S-o-B, checkpatch does complain about it. ;)

This might be due to the fact that you're using the same u-boot-nodtb.bin binary twice: once in binman section, and once in ITB. You can try to rename the binman entry to a different name, this might do the trick. See [1] for sample of imx8mq_evk conversion.

Is there any documentation available for this board that
needs adaptions with new build instructions? I was not able
to locate any doc for this board at all...

What I see is missing in this section is SECO and SCFW binaries.
Can i.MX8QM boot without those? Otherwise generated image will be unusable.

You can use "NAME" here I suppose.

And as well here, "NAME".

This binman configuration suggests that there are 2 binaries that
should be populated onto the bootable media: flash.bin and
u-boot.itb. Can you please convert them to use a single binary?
Sample code for this is also in [1].
