Hi!

I think we can improve this later. In the end, the structure should be either
the way DTs are structured in kernel OR we should have just one single config
for all SoCFPGA boards. The later is of course preferred.

For now, I'm tempted to apply this as-is so we at least have the groundwork in
place and can move on from that. What do you say ?

Best regards,
