As the hardware addresses have no utility other than for mchp hardware, it would follow that the license is not the issue.  

ps.  if mchp's goal is to preserve or manage the truthfulness of "if you're making money, we want to make money", then since "if you're not making money, then we're making money" is also true, there's really not likely to be a rational objection.

Yes, I exchanged several e-mails with them.They said several times that
they'll give us access to the XML pic device database, but this never
happened. But anyway, the pic .h and .c files, produced from the their
XML database wold have the same legal limitations as the current ones,
generated from MPASM include files: they can be used only for chips,
produced by Microchip. So no GPL.

I think the correct way to produce the GPL .h and .c files is directly
from the documentation, as Wes suggested. But even for this approach I'm
not sure if it is 100% legal. Has anybody take a detailed look into the
documentation if there is a statement which prohibits such actions?
