Need help on Linux PCIe

[Jagan Teki]

Hi,

I have few question on Linux PCIe subsystem, I am trying to understand
the PCIe on ARM platform.
1. Compared to PCI, PCIe have an extra port functionalists/services
which is implemented drivers/pci/pcie/* is it true?
2. PCIe root complex is same as Host controller drivers in linux drivers/host/*
3. As individual endpoint drivers are registered to pci_core as
pci_driver_register, then what is the common call for registering
individual HC driver to pci-core?
4. Can you list-down the basic and advanced functionalists supported
by HC driver in PCIe?
5. The PCIe port bus driver is common core? means no need to change w.r.t SOC?

Request for your comments.
