Some settings are board-specific but others are required by the
chipset. For example the Intel 3100 datasheet says software is
required to drive a handful of GPIOs in a particular way.

As long as the chipset code has to deal with GPIOs, it may as well try
to abstract away some of the boilerplate code and magic values, making
it easier to port to a new mainboard.

And the code already exists, so why not use it?
