This patch adds support to the Cadence PCIe controller in endpoint mode. Since pieces of source code are shared with the host driver (Root Complex mode), we create a new directory under drivers/pci dedicated to the Cadence PCIe controller. The common code is placed into drivers/pci/cadence/pcie-cadence.c and used by both the host and endpoint controller drivers.

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.
