ck804/mcp55 support code was written by Yinghai Lu who had docs under
NDA. Yinghai Lu has changed employers since then, and does not have
access to the docs anymore. No coreboot developer ever had docs for
Nvidia chipsets other than ck804/mcp55. Maybe someone else still has NDA
access to mcp55 docs, but I doubt it.

In theory, yes. I don't know about the current state.
