PCI Subsystem

What we have ported so far

• PCI data structures such as pci_dev, pci_bus, and so on.
• Mechanism to scan bus and build data structures during boot. Performed by pci_scan_root_bus(), and most code is in driver/pci/probe.c

Unfinished business

• Ways to go through all PCI device.
• pci_init_capabilities(): for each PCI device
• pci_fixup_device(): a lot quicks, maybe not useful
• pcie_aspm_init_link_state(): PCIe link state
• pci_iov_bus_range: all SR-IOV support
