Hello! I sent patch series for PCIe controller to linux-pci mailing list which should fix most of the problems with different Compex wifi cards on Armada 3720 boards, including Espressobin.

If you have still problems with different wifi cards on Espressobin, try above PCIe patches and let me know if they helped or not.
