      nubus: Add support for the driver model · 7f86c765
      Finn Thain authored
      This patch brings basic support for the Linux Driver Model to the
      NuBus subsystem.
      For flexibility, the matching of boards with drivers is left up to the
      drivers. This is also the approach taken by NetBSD. A board may have
      many functions, and drivers may have to consider many functional
      resources and board resources in order to match a device.
      This implementation does not bind drivers to resources (nor does it bind
      many drivers to the same board). Apple's NuBus declaration ROM design
      is flexible enough to allow that, but I don't see a need to support it
      as we don't use the "slot zero" resources (in the main logic board ROM).
      Eliminate the global nubus_boards linked list by rewriting the procfs
      board iterator around bus_for_each_dev(). Hence the nubus device refcount
      can be used to determine the lifespan of board objects.
