4) The cardbus CIS code treats the CIS_PTR as a mapping register if it is mentioned in the CIS. I don't have a spec handy to understand why the CIS_PTR is mentioned in the CIS, but allocating a memory range for it is certainly bogus. My patch ignores bar #6 to prevent the mapping. [The pccard spec says that BAR 0 and 7 (-1 and 6 in thic case since we did a minus one) is "reserved". The off by 1 error has been fixed. also bar=5 is invalid for IO maps, so we check it.] 5) The CIS code allocated duplicate resources to those already found by cardbus_add_resources(). The fix is to pass in the bar computed from the CIS instead of the particular resource ID for that bar, so bus_generic_alloc_resource succeeds in finding the old resource. [fixed, also removed superfluous (and incorrect) writing back to the PCI config space.] 7) The CIS code seems to use the wrong bit to determine rather a particular register mapping is for I/O or memory space. From looking at the two cards I have, it seems TPL_BAR_REG_AS should be 0x10 instead of 0x08. Otherwise, all registers that should be I/O mapped gain a second mapping in memory space. [Oops, the spec does say 0x10..., fixed] Submitted by: Justin Gibbs
