Hi Henry,
thanks for checking it...as i said i guess my behaviour is caused by known HW-issue with my R64 v1.1. Fullsize card (gen2?) not recognized in CN8.

We've verified the patchset on a fixed board.
The result shows that no matter how I swap the cards, it all works fine :)
Here are the logs:

in your logs i see you query also pci 2 (i had only tested 0+1), so i did it again
compex (fullsize) in front slot (cn25) and mt7612 (halfsize) in rear slot (cn8):
BPI-R64> pci enum PCI: Failed autoconfig bar 10 PCI: Failed autoconfig bar 10 BPI-R64> pci 0 Scanning PCI devices on bus 0 BusDevFun VendorId DeviceId Device Class Sub-Class _____________________________________________________________ 00.00.00 0x14c3 0x3258 Bridge device 0x04 00.01.00 0x14c3 0x3258 Bridge device 0x04 BPI-R64> pci 1 Scanning PCI devices on bus 1 BusDevFun VendorId DeviceId Device Class Sub-Class _____________________________________________________________ 01.00.00 0x168c 0x003c Network controller 0x80 BPI-R64> pci 2 Scanning PCI devices on bus 2 BusDevFun VendorId DeviceId Device Class Sub-Class _____________________________________________________________ 02.00.00 0x14c3 0x7612 Network controller 0x80 BPI-R64>
and swapped:
BPI-R64> pci enum Port1 link down PCI: Failed autoconfig bar 10 BPI-R64> pci 0 Scanning PCI devices on bus 0 BusDevFun VendorId DeviceId Device Class Sub-Class _____________________________________________________________ 00.00.00 0x14c3 0x3258 Bridge device 0x04 BPI-R64> pci 1 Scanning PCI devices on bus 1 BusDevFun VendorId DeviceId Device Class Sub-Class _____________________________________________________________ 01.00.00 0x14c3 0x7612 Network controller 0x80 BPI-R64> pci 2 No such bus BPI-R64>
afair compex-card was only recognized in front-slot, so same behaviour in uboot...
so first state in linux (5.8 with disabled sata):
root@bpi-r64:~# lspci 0000:00:00.0 PCI bridge: MEDIATEK Corp. Device 3258 0000:01:00.0 Network controller: Qualcomm Atheros QCA986x/988x 802.11ac Wirelesr 0001:00:01.0 PCI bridge: MEDIATEK Corp. Device 3258 0001:01:00.0 Network controller: MEDIATEK Corp. Device 7612
poweroff and swap cards
root@bpi-r64:~# lspci 00:00.0 PCI bridge: MEDIATEK Corp. Device 3258 01:00.0 Network controller: MEDIATEK Corp. Device 7612 root@bpi-r64:~#
i guess this is caused by known HW-Issues on R64 <=1.1 (power-limit / missing capacitors) and no driver-problem in uboot...
i have a additional half-size-card (intel wifi) but no extender to mount it so i replaced compex and pressed it down in cn8 with a remote control ;)

and it is recognized :) in linux it looks like this:
root@bpi-r64:~# lspci 0000:00:00.0 PCI bridge: MEDIATEK Corp. Device 3258 0000:01:00.0 Network controller: MEDIATEK Corp. Device 7612 0001:00:01.0 PCI bridge: MEDIATEK Corp. Device 3258 0001:01:00.0 Network controller: Intel Corporation Centrino Ultimate-N 6300 (re) root@bpi-r64:~#
i hope it get merged as soon as possible because it is the base for my Patches ;)
