Log Message:
New bus.h implementation/interface:
        - No more distinction between i/o-mapped and memory-mapped
          devices.  It's all "bus space" now, and space tags
          differentiate the space with finer grain than the
          bus chipset tag.
        - Add memory barrier methods.
        - Implement space alloc/free methods.
        - Implement region read/write methods (like memcpy to/from
          bus space).
This interface provides a better abstraction for dealing with
machine-independent chipset drivers.
