Linus Walleij 68a15eb7bd PCI: v3-semi: Add V3 Semiconductor PCI host driver
This PCI host bridge from V3 Semiconductor needs no further
introduction. An ancient driver for it has been sitting in
arch/arm/mach-integrator/pci_v3.* since before v2.6.12 and the
initial migration to git.

But we need to get the drivers out of arch/arm/* and get proper handling of
the old drivers, rewrite and clean up so the PCI maintainer can control the
mass of drivers without having to run all over the kernel. We also switch
swiftly to all the new infrastructure found in the PCI hosts as of late.

Some code is preserved so I have added an extensive list of authors in the
top comment section.

This driver probes with the following result:

  OF: PCI: host bridge /pciv3@62000000 ranges:
  OF: PCI:   No bus range found for /pciv3@62000000, using [bus 00-ff]

---help---
Adds support for the Intel Volume Management Device (VMD). VMD is a
secondary PCI host bridge that allows PCI Express root ports,
and devices attached to them, to be removed from the default
PCI domain and placed within the VMD domain. This provides
more bus resources than are otherwise possible with a
single domain. If you know your system provides one of these and
has devices attached to it, say Y; if you are not sure, say N.
To compile this driver as a module, choose M here: the
module will be called vmd.
