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
