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. config PCIE_LAYERSCAPE_GEN4 bool "Layerscape Gen4 PCIe support" depends on DM_PCI help Support PCIe Gen4 on NXP Layerscape SoCs, which may have one or several PCIe controllers. The PCIe controller can work in RC or EP mode according to RCW[HOST_AGT_PEX] setting. config FSL_PCIE_COMPAT string "PCIe compatible of Kernel DT" depends on PCIE_LAYERSCAPE || PCIE_LAYERSCAPE_GEN4 default "fsl,ls1012a-pcie" if ARCH_LS1012A default "fsl,ls1028a-pcie" if ARCH_LS1028A default "fsl,ls1043a-pcie" if ARCH_LS1043A default "fsl,ls1046a-pcie" if ARCH_LS1046A default "fsl,ls2080a-pcie" if ARCH_LS2080A default "fsl,ls1088a-pcie" if ARCH_LS1088A default "fsl,lx2160a-pcie" if ARCH_LX2160A default "fsl,ls1021a-pcie" if ARCH_LS1021A help This compatible is used to find pci controller node in Kernel DT to complete fixup. config PCIE_INTEL_FPGA bool "Intel FPGA PCIe support" depends on DM_PCI help Say Y here if you want to enable PCIe controller support on Intel FPGA, example Stratix 10. config PCI_MVEBU bool "Enable Armada XP/38x PCIe driver" depends on ARCH_MVEBU select DM_PCI select MISC help Say Y here if you want to enable PCIe controller support on Armada XP/38x SoCs. config PCI_KEYSTONE bool "TI Keystone PCIe controller" depends on DM_PCI help Say Y here if you want to enable PCI controller support on AM654 SoC. config PCIE_MEDIATEK bool "MediaTek PCIe Gen2 controller" depends on DM_PCI depends on ARCH_MEDIATEK help Say Y here if you want to enable Gen2 PCIe controller, which could be found on MT7623 SoC family. endif
