I suspect that is because only a few files (still) contain any
CVS-specific information, since we're using git, not CVS.

The answer to your question is: to me, at least, it is not clearly
compliant because it changes the author, which should never be done.
However, these information lines are technical in nature, not part of
the actual source code as such, and it might thus be ok.

But my first answer would actually be a question: why on Earth do
you use CVS for a project that is managed with git? If you used git,
the issue you raise would simply not exist.

Use git. :)

It is free, it is open source, it can (and should) be installed on
every developer's machine to help them manage their own developments,
and on servers to help concentrate said developments, any git copy of
U-Boot can easily be kept in sync with our mainline repository (or any
of the specialized custodian repos)... There really is no reason to use
anything else than git.
