Sorry, I suddenly got busy (my second son arrived a few days earlier
than expected).

I just sent a proper patch with the proposal I made last week, after
testing on ClearFog and Armada XP GP. Note that on ClearFog, I only
tested that it fixes the panic at boot, since I didn't had any
mini-PCIe devices at hand. On Armada XP GP, I verified that an E1000E
NIC was still working as expected. Therefore, it would be useful if
you could test on your ClearFog platform with PCI devices connected.

Thanks a lot and sorry for the delay.

Best regards,

Thomas
