Hi Gaurav!
Nice to see another imx8 machine being contributed! I'm impressed how close you
stick to the imx8mp, both in terms of structuring this series as well as the
code.
I've built your series and ran the functional test. Comments below.

Looks like these lists are sorted alphabetically. Shall we preserve that?

This DTB offset is the one for the imx8mp-evk, and in fact the console log
confirms it. Both machines seem to be so similar that the test passes anyway.
What you need is the offset in the "disk.raw" image that gets extracted from
above file. Open "disk.raw" in a hex editor and search for "imx8mm-evk", then
determine the offset of the preceeding "d00df00d" DTB magic. That is your
offset.
Best regards,
Bernhard
