call for the board's memory space to be PCI_MAPREG_MEM_TYPE_32BIT_1M or
PCI_MAPREG_MEM_TYPE_32BIT depending on the board ID. Also, remove a
bogus extra argument to an interrupt-establishment-error printf. Problems
pointed out by Jarkko Torppa <torppa@cute.fi> in PR 3753, but fixed slightly
differently than he suggested.
- 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.
