I don't know what the best grouping for this stuff would be. Maybe I'd
go for grouping by hardware blocks rather than functionality like
errors. Cc: Lucas, Matt, Rodrigo, just to pick a few names who might
have a better idea.

Just don't dump register macros to a single file that will bloat to
become unmanageable.

BR,
Jani.


PS. Please also don't top-post on mailing lists.
