- 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.
