/*
  nubus.h: various definitions and prototypes for NuBus drivers to use.

  Originally written by Alan Cox.

  Hacked to death by C. Scott Ananian and David Huggins-Daines.
  
  Some of the constants in here are from the corresponding
  NetBSD/OpenBSD header file, by Allen Briggs.  We figured out the
  rest of them on our own. */
