I got 1/5, 3/5, and 5/5 (and no cover letter).  Is there a 2/5 and a
4/5?  Not sure if I should wait for more, or review these three as-is?
I sent all 5 together with cover letter. Do you want me to send it again ?

If CONFIG_PCIEPORTBUS is not enabled in kernel then initialing
struct pci_host_bridge PCIe specific native_* members to "1" is
incorrect. So protect the PCIe specific member initialization
with CONFIG_PCIEPORTBUS.
