I can't see your name in git log that's why I expect this is maybe your
the first submission. How can I trust that you will test this board
regularly that make sense to have it in the tree?

I don't have this board that's why it can be broken quickly.

There are a lot of versions with different chips on it. It will be good
to exactly write what version this is going to support.
Also there is different amount of flash on 1EL version based on
https://shop.trenz-electronic.de/en/Products/Trenz-Electronic/TE08XX-Zynq-UltraScale/TE0820-Zynq-UltraScale/

Also this is SOM and it requires Carrier board to know wiring. What
carrier board is this configuration for?

This is Trenz that's why it you should use trenz instead of zynqmp.

Trenz,

Add trenz to vendor-prefixes.txt in the Linux kernel and use it here.

Based on Rob Herring this shouldn't be here.

This and stuff below looks like c&p from zcu102 version which is incorrect.

I am going to skip the rest of this patch because questions above needs
to be answered first.
