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.

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.

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.

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.)
1997-04-10 23:21:29 +00:00

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.
