I agree that it does not make sense to add configurations that no one else
can try and use. The goal is that others can easily try out the IP. I want to
provide the FPGA image to others who are interested. It won't be many of
course.

You are right, it is not product, which is addressed to end users. It is a
demonstration configuration for developers. Isn't that valid for all evaluation
boards? As a developer I'm very happy if I can do evaluation and development
without any vendor tree. I can do that now with the ZCU104. So a big thank
you from me for your work!

This dt binding example is already there.

So a device tree like this won't be accepted?
