I think it is a worthy goal to have a generic Linux for a generic LEON, but before I support this particular project, I would like to discuss one thing.
Your VHDL target must be in use by someone long term. I do not even care if Opencores or whoever accepts it, but there must be a nonzero user base, now and in the future. I do not want to add it then to rip it out like AP-1000. For comparison, a recurring topic on Sparclinux list is a removal of sun4 and even sun4c. I was ready to support David Foulds' MMU before, but it never materialized.

"Throw out the sun hardware stuff" sounds broken. Look closer at CONFIG_SUN4. So far I do not see why you need a separate architecture. Sure, throwing the stuff away helps you to finish your diploma on time, but then I have to maintain what's left.

Discuss early, discuss often. Use Sparclinux@vger.kernel.org and, perhaps, the Leon list at (bleah!) yahoogroups. Learn to send patches, and be ready to stay as a patch for a while (a year or so). I think Jeff Dike's UML is a model of project management for you (http://user-mode-linux.sourceforge.net/). He stayed outside AND in close contact while he proved that the project was viable, then Linus took it.
Good luck and send those patches, -- Pete - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
