How do you know that it is complete? I doubt that we have (even links
to) complete documentation for anything besides superio chips.

It may be available from the manufacturer, Intel. Please talk to them.
If you can acquire documentation and the permission to redistribute,
then more information is of course very welcome on the datasheets
web page.

Because that is already immediately obvious for someone who looks at
the documentation that *is* available, or for someone with experience
from PC firmware development, or for someone who starts reading the
coreboot source code and tries to look up what the meaning of the
code is, or for someone who gets told about this fact e.g. via email.

I'm sorry that none of this is sufficient for you.
