We have completed pci_autoconfig, npe.
Let's go ahead with pcie. The pcie module are compiled from several
source files. You can guess their purpose from the file name.

pcie is a misc module, it provides
interface to manipulate a pcie framework. There is no devinfo node
related to this module, but you can find many reference call in other
driver modules, such as npe we have just read.
