For the general idea, read
For more details,
http://www.netbsd.org/Documentation/, there look especially at the
Device Driver Writing Guide and the Kernel Programming FAQ.
Most NetBSD kernel interfaces written in modern times have a man
page in chapter 9. You'll probably need to read pmap(9), bus_space(9)
and bus_dma(9) when porting to a new architecture, although often
(that is, with a same-cpu port) you'll be able to use an existing
port as a guideline, and maybe able to call shared code ...
