PNPACPI: fix non-memory address space descriptor handling
Fix resource_type handling for QWORD, DWORD, and WORD Address Space Descriptors. Previously we ignored the resource_type, so I/O ports and bus number ranges were incorrectly parsed as memory ranges. Sample PCI root bridge resources from HP rx2600 before this patch: # cat /sys/bus/pnp/devices/00:02/resources state = active mem 0x0-0x1f mem 0x0-0x3af mem 0x3e0-0x1fff mem 0x80000000-0x8fffffff With this patch: # cat /sys/bus/pnp/devices/00:02/resources state = active io 0x0-0x3af io 0x3e0-0x1fff mem 0x80000000-0x8fffffff mem 0x80004000000-0x80103fffffe Changes: 0x0-0x1f PCI bus number range was incorrectly reported as memory, now not reported at all 0x0-0x3af I/O port range was incorrectly reported as memory 0x3e0-0x1fff I/O port range was incorrectly reported as memory 0x80004000000-0x80103fffffe memory range wasn't reported at all because we only support PNP_MAX_MEM (4) memory resources Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Len Brown <len.brown@intel.com>
