df88882d80 - Add a bus space method for getting the translation for a window. 
- Add sysarch methods for "get bus window count", "get bus window",
  and "pci conf read/write".

These are a hack, but they're what's necessary in order to make
XFree86 work in its current state.

de974ff82d Add an internal bus space method alpha_bus_space_translate(), which 
provides a method to translate an address on an I/O bus into a sysBus
address, along with acccess method information.

781149bb12 Handle the case where PCI dense memory and PCI sparse memory don't 
overlap; don't require allocation from the dense extent if the PCI
memory address isn't mapped into dense space.

Also, make sure to return an error if a liner mapping is requested
and dense space is not available (not just not requested).

51f4c69ad4 Clarify what appear to the untrained eye to be two magic constants (the 
address shift and access size shift), and allow them to be overridden
by chip-specific code, if necessary.

611012d836 Make the copy_region methods do overlapping copies properly. Fixes

ed2ec4869c Update for Chris Demetriou's changes made to the bus.h interface: 
- bus_space_copy -> bus_space_copy_region (for consistency)
- "cacheable" argument becomes a "flags" argument instead, with
  BUS_SPACE_MAP_CACHEABLE and BUS_SPACE_MAP_LINEAR flags currently
  defined.

aa7a2876e6 Treat bus space tags more like pci chipset tags and bus dma tags: allocate 
them statically within a chipset's state structure, and pass them to
the *_bus_{io,mem}_init() functions.

9dc7578cb5 move and split pcs_bus_{mem,io}_common.c, so that: 
(1) object code can be shared (where the hardware makes that possible), and
(2) so that the file names better describe the systems which use them.  (the
    pci_swiz* files are for machines whose PCI interfaces require address
    "swizzling."  Later, there will be probably be other sets, e.g. pci_bwx*
    for machines whose chipsets can easily deal with the Alpha BWX extensions
    when doing device accesses.)

0a500fffa0 update to allow PCI bus interfaces that wish to allocate static 
extent storage per interface unit (e.g. dwlpx, where there can be multiple
units per machine) to do so.  Inspired by discussion with and changes from
Matt Jacob.

1b03f1bca7 update for new bus.h macros. bus_io_* and bus_mem_* integrated into 
single bus_space_* framework.  Unfortunately, bus_space_{read,write}_*
operations still imply barriers.  That will change soon.

8df74fa62a wrap __STRING() in a #define so that its argument, which must be 
expanded by the preprocessor, will be.  Problem pointed out by Matt
Thomas.

c6dd609e7f gross hack to get around the fact that there are currently devices with 
common back-ends that live on multiple very-different busses (e.g. PCI and
TC), which need bus-specific DMA mapping support.  As a nice side effect,
this will allow the especially nasty (vtophys(va) | 0x40000000) expressions
to go away in favor of less nasty bus-specific function calls.

04645aa7ad chipset 'bus' functions that seem to be common to all host bus 
adapters that exist in single-CPU systems.  APECS, CIA, and LCA
all use this, but with different #defines.
