With most open source hardware efforts, like this, it's not really so much circuit design as it is just code. All of the open source efforts I've seen revolve around digital circuits, which are written in some kind of RTL and turned into an actual circuit by completely automatic processes. It's still great, and I fully support them, but there's a massive amount of non-digital that's crucial to getting these systems up and running. Not to mention that even if you have an open source CPU RTL, for example, you'll need access to a closed-source and often NDA-blocked PDK (process development kit), fabrication company, etc. I remember seeing some efforts at open sourcing the PDK part as well, but remember being unimpressed.
