For me this is not a problem because on Linux side it is not increasing
build time.
I want to see the value for community. All xilinx platforms are
evaluation generic purpose boards which are showing how to connect stuff
together.
On the other hand this is real product.

I would let arm-soc maintainer to decide if this is fine or not. I
definitely don't want to end up in situation that we will have dts for
real products which are not bringing any value for others.

Thanks,
Michal
