Warner Losh e4b59fc500 Add support for subtractive decoding bridges. These bridges pass all ... signals to addresses to the child busses. Typically, ProgIf of 1 means a subtractive bridge. However, Intel has a whole lot of ones with a ProgIf of 80 that are also subtractive. We cope with these bridges too. This eliminates hw.pci.allow_unsupported_io_range because that had almost the same effect as these patches (almost means 'buggy'). Remove the bogus checks for ISA bus locations: these cycles aren't special and are only passed by transparent bridges. We allow any range to succeed. If the range is a superset of the range that's decoded, trim the resource to that range. Otherwise, pass the range unchanged. This will change the location that PC Card and CardBus cards are attached. This might bogusly cause some overlapping allocation that wasn't present before, but the overlapping fixes need to be in the pci level. There's also a few formatting changes here.		2004-01-11 06:52:31 +00:00
