I should be sleeping at 2am instead - this would fragment the CFR into 'actual' tags rather than one effective structure. I still like the theory of it, but implementing it with CBTABLE rules would mean gathering up forms. Besides, we currently offload the option table responsibility to the board.

Is it worth dedicated `CB_TAG_CFR_{SILICON,BOARD}_FORM` tags? We have to exclude drivers.
