1menuconfig PCI 2 bool "PCI support" 3 default y if PPC 4 help 5 Enable support for PCI (Peripheral Interconnect Bus), a type of bus 6 used on some devices to allow the CPU to communicate with its 7 peripherals. 8 9if PCI 10 11config DM_PCI 12 bool "Enable driver model for PCI" 13 depends on DM 14 help 15 Use driver model for PCI. Driver model is the new method for 16 orgnising devices in U-Boot. For PCI, driver model keeps track of 17 available PCI devices, allows scanning of PCI buses and provides 18 device configuration support. 19 20config DM_PCI_COMPAT 21 bool "Enable compatible functions for PCI" 22 depends on DM_PCI 23 help 24 Enable compatibility functions for PCI so that old code can be used 25 with CONFIG_DM_PCI enabled. This should be used as an interim 26 measure when porting a board to use driver model for PCI. Once the 27 board is fully supported, this option should be disabled. 28 29config PCI_AARDVARK 30 bool "Enable Aardvark PCIe driver" 31 default n 32 depends on DM_PCI 33 depends on ARMADA_3700 34 help 35 Say Y here if you want to enable PCIe controller support on 36 Armada37x0 SoCs. The PCIe controller on Armada37x0 is based on 37 Aardvark hardware. 38 39config PCI_PNP 40 bool "Enable Plug & Play support for PCI" 41 depends on PCI || DM_PCI 42 default y 43 help 44 Enable PCI memory and I/O space resource allocation and assignment. 45 46config PCIE_ECAM_GENERIC 47 bool "Generic ECAM-based PCI host controller support" 48 default n 49 depends on DM_PCI 50 help 51 Say Y here if you want to enable support for generic ECAM-based 52 PCIe host controllers, such as the one emulated by QEMU. 53 54config PCIE_DW_MVEBU 55 bool "Enable Armada-8K PCIe driver (DesignWare core)" 56 depends on DM_PCI 57 depends on ARMADA_8K 58 help 59 Say Y here if you want to enable PCIe controller support on 60 Armada-8K SoCs. The PCIe controller on Armada-8K is based on 61 DesignWare hardware. 62 63config PCI_RCAR_GEN2 64 bool "Renesas RCar Gen2 PCIe driver" 65 depends on DM_PCI 66 depends on RCAR_32 67 help 68 Say Y here if you want to enable PCIe controller support on 69 Renesas RCar Gen2 SoCs. The PCIe controller on RCar Gen2 is 70 also used to access EHCI USB controller on the SoC. 71 72config PCI_SANDBOX 73 bool "Sandbox PCI support" 74 depends on SANDBOX && DM_PCI 75 help 76 Support PCI on sandbox, as an emulated bus. This permits testing of 77 PCI feature such as bus scanning, device configuration and device 78 access. The available (emulated) devices are defined statically in 79 the device tree but the normal PCI scan technique is used to find 80 then. 81 82config PCI_TEGRA 83 bool "Tegra PCI support" 84 depends on TEGRA 85 depends on (TEGRA186 && POWER_DOMAIN) || (!TEGRA186) 86 help 87 Enable support for the PCIe controller found on some generations of 88 Tegra. Tegra20 has 2 root ports with a total of 4 lanes, Tegra30 has 89 3 root ports with a total of 6 lanes and Tegra124 has 2 root ports 90 with a total of 5 lanes. Some boards require this for Ethernet 91 support to work (e.g. beaver, jetson-tk1). 92 93config PCI_XILINX 94 bool "Xilinx AXI Bridge for PCI Express" 95 depends on DM_PCI 96 help 97 Enable support for the Xilinx AXI bridge for PCI express, an IP block 98 which can be used on some generations of Xilinx FPGAs. 99 100config PCIE_LAYERSCAPE 101 bool "Layerscape PCIe support" 102 depends on DM_PCI 103 help 104 Support Layerscape PCIe. The Layerscape SoC may have one or several 105 PCIe controllers. The PCIe may works in RC or EP mode according to 106 RCW[HOST_AGT_PEX] setting. 107 108endif 109
