| Enable support for PCI (Peripheral Interconnect Bus), a type of bus | |
| used on some devices to allow the CPU to communicate with its | |
| peripherals. | |

| config DM_PCI | |
| bool "Enable driver model for PCI" | |
| depends on DM | |
| help | |
| Use driver model for PCI. Driver model is the new method for | |
| orgnising devices in U-Boot. For PCI, driver model keeps track of | |
| available PCI devices, allows scanning of PCI buses and provides | |
| device configuration support. | |
| config DM_PCI_COMPAT | |
| bool "Enable compatible functions for PCI" | |
| depends on DM_PCI | |
| help | |
| Enable compatibility functions for PCI so that old code can be used | |
| with CONFIG_DM_PCI enabled. This should be used as an interim | |
| measure when porting a board to use driver model for PCI. Once the | |
| board is fully supported, this option should be disabled. | |

| help | |
| Say Y here if you want to enable PCIe controller support on | |
| Armada37x0 SoCs. The PCIe controller on Armada37x0 is based on | |
| Aardvark hardware. | |
| config PCI_PNP | |

| help | |
| Say Y here if you want to enable PCIe controller support on | |
| Renesas RCar Gen2 SoCs. The PCIe controller on RCar Gen2 is | |
| also used to access EHCI USB controller on the SoC. | |
| config PCI_SANDBOX | |
| bool "Sandbox PCI support" | |
| depends on SANDBOX && DM_PCI | |
| help | |
| Support PCI on sandbox, as an emulated bus. This permits testing of | |
| PCI feature such as bus scanning, device configuration and device | |
| access. The available (emulated) devices are defined statically in | |
| the device tree but the normal PCI scan technique is used to find | |
| then. | |

| Enable support for the PCIe controller found on some generations of | |
| Tegra. Tegra20 has 2 root ports with a total of 4 lanes, Tegra30 has | |
| 3 root ports with a total of 6 lanes and Tegra124 has 2 root ports | |
| with a total of 5 lanes. Some boards require this for Ethernet | |
| support to work (e.g. beaver, jetson-tk1). | |
| config PCI_XILINX | |
| bool "Xilinx AXI Bridge for PCI Express" | |

| Enable support for the Xilinx AXI bridge for PCI express, an IP block | |
| which can be used on some generations of Xilinx FPGAs. | |
| config PCIE_LAYERSCAPE | |
