I prepared the package and uploaded to the github (I maintain UEFI for Armada).

No, type + revision is sufficitent, thanks.

Yes, that's sufficient. Recently Baruch fixed the PCIE reset handling
in the Linux kernel on McBin (merged to linux-next a week ago), so the
thing you see may be related.

I think it will be really worth for you to check the pcie-host-generic
ECAM driver. With the SW you have, the easiest way without recompiling
anything should be using ACPI. Once in grub, edit the linux
commandline and add:
acpi=force console=ttyS0,115200

I hope that works, please let know.

Best regards,
Marcin
