pci: Use helper to find device's root bus in pci_find_domain()

Currently pci_find_domain() performs two functions - it locates the PCI
root bus above the given bus, then looks up that root bus's domain number.
This patch adds a helper function to perform the first task, finding the...

pci: Replace pci_find_domain() with more general pci_root_bus_path()

pci_find_domain() is used in a number of places where we want an id for a
whole PCI domain (i.e. the subtree under a PCI root bus). The trouble is
that many platforms may support multiple independent host bridges with no...

pci: Add root bus argument to pci_get_bus_devfn()

pci_get_bus_devfn() interprets a full PCI address string to give a PCIBus *
and device/function number within that bus. Currently it assumes it is
working on an address under the primary PCI root bus. This patch extends...

pci: Add root bus parameter to pci_nic_init()

At present, pci_nic_init() and pci_nic_init_nofail() assume that they will
only create a NIC under the primary PCI root. As we add support for
multiple PCI roots, that may no longer be the case. This patch adds a root...

pci: Simpler implementation of primary PCI bus

Currently pci_find_primary_bus() searches the list of root buses for one
with domain 0. But since host buses are always registered with domain 0,
this just amounts to finding the only PCI host bus. The only remaining...

pci: Remove domain from PCIHostBus

There are now no users of the domain field of PCIHostBus, so remove it
from the structure, and as a parameter from the pci_host_bus_register()
function which sets it.

pci: Fold host_buses list into PCIHostState functionality

The host_buses list is an odd structure - a list of pointers to PCI root
buses existing in parallel to the normal qdev tree structure. This patch
removes it, instead putting the link pointers into the PCIHostState...
