pci: PCIe driver for Marvell Armada 370/XP systems
This driver implements the support for the PCIe interfaces on the
Marvell Armada 370/XP ARM SoCs. In the future, it might be extended to
cover earlier families of Marvell SoCs, such as Dove, Orion and
Kirkwood.
The driver implements the hw_pci operations needed by the core ARM PCI
code to setup PCI devices and get their corresponding IRQs, and the
pci_ops operations that are used by the PCI core to read/write the
configuration space of PCI devices.
Since the PCIe interfaces of Marvell SoCs are completely separate and
not linked together in a bus, this driver sets up an emulated PCI host
bridge, with one PCI-to-PCI bridge as child for each hardware PCIe
interface.
In addition, this driver enumerates the different PCIe slots, and for
those having a device plugged in, it sets up the necessary address
decoding windows, using the mvebu-mbus driver.

PCI: faraday: Add Faraday Technology FTPCI100 PCI Host Bridge driver
Add a host bridge driver for the Faraday Technology FPPCI100 host bridge,
used for Cortina Systems Gemini SoC (SL3516) PCI Host Bridge.
This code is inspired by the out-of-tree OpenWRT patch and then extensively
rewritten for device tree and using the modern helpers to cut down and
modernize the code to all new PCI frameworks. A driver exists in U-Boot as
well.
Tested on the ITian Square One SQ201 NAS with the following result in the
boot log (trimmed to relevant parts):

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.

pci: PCIe driver for Marvell Armada 370/XP systems
This driver implements the support for the PCIe interfaces on the
Marvell Armada 370/XP ARM SoCs. In the future, it might be extended to
cover earlier families of Marvell SoCs, such as Dove, Orion and
Kirkwood.
The driver implements the hw_pci operations needed by the core ARM PCI
code to setup PCI devices and get their corresponding IRQs, and the
pci_ops operations that are used by the PCI core to read/write the
configuration space of PCI devices.
Since the PCIe interfaces of Marvell SoCs are completely separate and
not linked together in a bus, this driver sets up an emulated PCI host
bridge, with one PCI-to-PCI bridge as child for each hardware PCIe
interface.
In addition, this driver enumerates the different PCIe slots, and for
those having a device plugged in, it sets up the necessary address
decoding windows, using the mvebu-mbus driver.
