I my respin I used:
append root=PARTUUID=%PARTUUID% rootwait rw
The UUID is created in a post-build.sh script and set it in
extlinux.conf and genimage.cfg
With that the image would not limited to be located on the SD card.

Do you need 240MB here?

Thanks for pointing this out. I will change it.
In the long term, we could probably use a common genimage.cfg too.

Good idea. Will change it.

On my tests, I noticed that if I build U-Boot 2022.01 + TF-A mainline,
then the kernel 5.16 does not boot.
Using TF-A from the NXP BSP allows me to boot 5.16 without issues.
I will try to investigate why this happens with imx8mm-evk, as your
board does not show issues.
Thanks

You had some comments from Heiko on this patch, and you said you would
come back with a newer version, but unless I missed it, I couldn't find
a v3.
I'll now mark this v2 as Changes Requested in patchwork, so if you
don't submit a v3, we will most likely forget about this topic. But it
would be good to have a defconfig for the i.MX8MM EVK.
Thanks a lot!
Thomas
