Agreed.

Either as the first step is fine by me.

I think they're still useful for deciding the contents of intel_reg
dump, for the platforms defined anyway. I wouldn't throw them away.

I wouldn't object to incorporating the information in the tool at build
time. But if nobody has the time to do that, just let it be until we
have figured out a way to generate the info, if ever.

Since the decoding info is starting to be out of date, especially the
builtin stuff, maybe it should be made optional via a --decode parameter
similar to --binary, and default to off?

BR,
Jani.
