| help |
| 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. |

| config PCI_PNP |
| bool "Enable Plug & Play support for PCI" |
| depends on PCI || DM_PCI |
| default y |

| Enable PCI memory and I/O space resource allocation and assignment. |

| config PCIE_ECAM_GENERIC |
| bool "Generic ECAM-based PCI host controller support" |
| default n |
| depends on DM_PCI |
| help |
| Say Y here if you want to enable support for generic ECAM-based |
| PCIe host controllers, such as the one emulated by QEMU. |

| config PCIE_DW_MVEBU |
| bool "Enable Armada-8K PCIe driver (DesignWare core)" |
| depends on DM_PCI |
| depends on ARMADA_8K |
| help |
| Say Y here if you want to enable PCIe controller support on |
| Armada-8K SoCs. The PCIe controller on Armada-8K is based on |
| DesignWare hardware. |

| 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. |

| config PCI_TEGRA |
| bool "Tegra PCI support" |
| depends on TEGRA |
| depends on (TEGRA186 && POWER_DOMAIN) || (!TEGRA186) |
| help |
| 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" |
| depends on DM_PCI |
| help |
| 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 |
| bool "Layerscape PCIe support" |
| depends on DM_PCI |
| help |
| Support Layerscape PCIe. The Layerscape SoC may have one or several |
| PCIe controllers. The PCIe may works in RC or EP mode according to |
| RCW[HOST_AGT_PEX] setting. |
