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
12 bool "Enable driver model for PCI"
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.
21 bool "Enable compatible functions for PCI"
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.
30 bool "Enable Aardvark PCIe driver"
33 depends on ARMADA_3700
35 Say Y here if you want to enable PCIe controller support on
36 Armada37x0 SoCs. The PCIe controller on Armada37x0 is based on
40 bool "Enable Plug & Play support for PCI"
41 depends on PCI || DM_PCI
44 Enable PCI memory and I/O space resource allocation and assignment.
46 config PCIE_ECAM_GENERIC
47 bool "Generic ECAM-based PCI host controller support"
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.
55 bool "Enable Armada-8K PCIe driver (DesignWare core)"
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
64 bool "FSL PowerPC PCIe support"
67 Say Y here if you want to enable PCIe controller support on FSL
68 PowerPC MPC85xx, MPC86xx, B series, P series and T series SoCs.
69 This driver does not support SRIO_PCIE_BOOT feature.
72 bool "MPC85XX PowerPC PCI support"
75 Say Y here if you want to enable PCI controller support on FSL
79 bool "Renesas RCar Gen2 PCIe driver"
83 Say Y here if you want to enable PCIe controller support on
84 Renesas RCar Gen2 SoCs. The PCIe controller on RCar Gen2 is
85 also used to access EHCI USB controller on the SoC.
88 bool "Renesas RCar Gen3 PCIe driver"
92 Say Y here if you want to enable PCIe controller support on
93 Renesas RCar Gen3 SoCs.
96 bool "Sandbox PCI support"
97 depends on SANDBOX && DM_PCI
99 Support PCI on sandbox, as an emulated bus. This permits testing of
100 PCI feature such as bus scanning, device configuration and device
101 access. The available (emulated) devices are defined statically in
102 the device tree but the normal PCI scan technique is used to find
106 bool "Tegra PCI support"
108 depends on (TEGRA186 && POWER_DOMAIN) || (!TEGRA186)
110 Enable support for the PCIe controller found on some generations of
111 Tegra. Tegra20 has 2 root ports with a total of 4 lanes, Tegra30 has
112 3 root ports with a total of 6 lanes and Tegra124 has 2 root ports
113 with a total of 5 lanes. Some boards require this for Ethernet
114 support to work (e.g. beaver, jetson-tk1).
117 bool "Xilinx AXI Bridge for PCI Express"
120 Enable support for the Xilinx AXI bridge for PCI express, an IP block
121 which can be used on some generations of Xilinx FPGAs.
123 config PCIE_LAYERSCAPE
124 bool "Layerscape PCIe support"
127 Support Layerscape PCIe. The Layerscape SoC may have one or several
128 PCIe controllers. The PCIe may works in RC or EP mode according to
129 RCW[HOST_AGT_PEX] setting.
131 config PCIE_LAYERSCAPE_GEN4
132 bool "Layerscape Gen4 PCIe support"
135 Support PCIe Gen4 on NXP Layerscape SoCs, which may have one or
136 several PCIe controllers. The PCIe controller can work in RC or
137 EP mode according to RCW[HOST_AGT_PEX] setting.
139 config PCIE_INTEL_FPGA
140 bool "Intel FPGA PCIe support"
143 Say Y here if you want to enable PCIe controller support on Intel
144 FPGA, example Stratix 10.
147 bool "Enable Armada XP/38x PCIe driver"
148 depends on ARCH_MVEBU
152 Say Y here if you want to enable PCIe controller support on
156 bool "TI Keystone PCIe controller"
159 Say Y here if you want to enable PCI controller support on AM654 SoC.
162 bool "MediaTek PCIe Gen2 controller"
164 depends on ARCH_MEDIATEK
166 Say Y here if you want to enable Gen2 PCIe controller,
