x86/PCI: Include function number in $PIR table dump
Contrary to the PCI BIOS specification[1] some systems include the PCI
function number for motherboard devices in their $PIR table, e.g. this
is what the Tyan Tomcat IV S1564D board reports:
00:14 slot=01
0:60/deb8
1:61/deb8
2:62/deb8
3:63/deb8
00:13 slot=02
0:61/deb8
1:62/deb8
2:63/deb8
3:60/deb8
00:12 slot=03
0:62/deb8
1:63/deb8
2:60/deb8
3:61/deb8
00:11 slot=04
0:63/deb8
1:60/deb8
2:61/deb8
3:62/deb8
00:07 slot=00
0:00/deb8
1:00/deb8
2:00/deb8
3:00/deb8
00:07 slot=00
0:00/deb8
1:00/deb8
2:00/deb8
3:63/deb8
Print the function number then in the debug $PIR table dump:
00:14.0 slot=01
0:60/deb8
1:61/deb8
2:62/deb8
3:63/deb8
00:13.0 slot=02
0:61/deb8
1:62/deb8
2:63/deb8
3:60/deb8
00:12.0 slot=03
0:62/deb8
1:63/deb8
2:60/deb8
3:61/deb8
00:11.0 slot=04
0:63/deb8
1:60/deb8
2:61/deb8
3:62/deb8
00:07.1 slot=00
0:00/deb8
1:00/deb8
2:00/deb8
3:00/deb8
00:07.2 slot=00
0:00/deb8
1:00/deb8
2:00/deb8
3:63/deb8
