It is started with zedboard which was made by Avnet and Digilent
together with Xilinx help that's why it was added there.
There is cooperation between Xilinx and Digilent on these boards that's
why they are added there.

For your case this is private board which I expect none can buy as a kit
that's why it should be in separate folder.

I did play with it and it is not that hard. I did just these changes
and move stuff to your folder.

We did that in past but for example if you look at zybo which was added
the last coding style is fixed there.

As you see all stuff is coming to Kconfig that's why I hope that we can
reduce number of configurations files for every board.
Also currently as you see buildman is reporting this as a bug now.

Thanks,
