registers. This is so that I can read an SMC 93cx6 through the
32-bit registers of the ADMtek ADM8211 802.11 wireless MAC.
Adapt aic to choose 8-bit registers.
- 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.
