5f14f7d783 pci: rmobile: Add RCar Gen2 PCIe controller driver
Add driver for the Renesas RCar PCIe controller present on Gen2 SoCs.
The PCIe on Gen2 is used both to connect external PCIe peripherals as
well as access the on-SoC USB EHCI controller.

3675cb044e PCI: Add driver for a 'pci-host-ecam-generic' host controller
QEMU emulates such a device with '-machine virt,highmem=off' on ARM.
The 'highmem=off' part is required for things to work as the PCI code
in U-Boot doesn't seem to support 64-bit BARs.

80afc63fc3 pci: layerscape: add pci driver based on DM
There are more than five kinds of Layerscape SoCs. unfortunately,
PCIe controller of each SoC is a little bit different. In order
to avoid too many macro definitions, the patch addes a new
implementation of PCIe driver based on DM. PCIe dts node is
used to describe the difference.

182ba1a7df pci: mvebu: Add PCIe driver for Armada-8K
This patch adds a driver for the PCIe controller integrated in the
Marvell Armada-8K SoC. This controller is based on the DesignWare
IP core.

The original version was written by Shadi and Yehuda. I ported this
driver to the latest mainline U-Boot version with DM support.

Tested on the Marvell DB-88F8040 Armada-8K eval board.

a29e45a9c4 pci: xilinx: Add a driver for Xilinx AXI to PCIe bridge
This patch adds a driver for the Xilinx AXI bridge for PCI express, an
IP block which can be used on some generations of Xilinx FPGAs. This is
mostly a case of implementing PCIe ECAM specification, but with some
quirks about what devices are valid to access.

bbc5b36b25 pci: tegra: port to standard clock/reset/pwr domain APIs
Tegra186 supports the new standard clock, reset, and power domain APIs.
Older Tegra SoCs still use custom APIs. Enhance the Tegra PCIe driver so
that it can operate with either set of APIs.

On Tegra186, the BPMP handles all aspects of PCIe PHY (UPHY) programming.
Consequently, this logic is disabled too.
