NVIDIA to provide documentation for Nouveau

You guys seem to be talking about two different things and I'm not sure any effective communication is going on here. In one case you have a general statement that firmware, especially firmware that is capable of being updated, can harbor persistent threats, backdoors, etc. EFI provides standard capabilities, like network support, which may make these kinds of threats easier to design or more useful. These risk of these kinds of threats though are unchanged whether SecureBoot(tm) exists or not and so to rope in Secure Boot into the discussion is to muddy the waters about two different threats/risks and two different responses.
