1. Done.
2. I suppose I don't really get the point? I'm already authoring the commits, so that counts as "credit for my work," or something like that. I think that the license covers permissions already (except BSD licenses allow code to be forked and made closed-source, as I understand, but I'm not a lawyer), but I guess I can think about it?

But I did realise that I had copied in Intel copyrights with the file header on entirely new files, so I removed those. Let me know if I shouldn't do this, or if I should push a fix-up to remove this copyright in KabylakeOpenBoardPkg/BaseEcLib/EcCommands.c, which is also a new file but already reviewed.
