> A mainboard isn't a chip. […]

adding the mainboard as a chip allows me to have a mainboard specific header to expose additional constants to the device tree. if you look at the CL above this, I've added net names in place of the #defined GPIOs.

I'd be open to updating the parsing script to add said functionality for board definitions, but I expect that to affect more of the community and require more discussion and engagement
