menuconfig PCI
bool "PCI support"
default y if PPC
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.
if PCI
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_AARDVARK
bool "Enable Aardvark PCIe driver"
default n
depends on DM_PCI
depends on DM_GPIO
depends on ARMADA_3700
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
bool "Enable Plug & Play support for PCI"
depends on PCI || DM_PCI
default y
help
Enable PCI memory and I/O space resource allocation and assignment.
config PCI_REGION_MULTI_ENTRY
bool "Enable Multiple entries of region type MEMORY in ranges for PCI"
depends on PCI || DM_PCI
default n
help
Enable PCI memory regions to be of multiple entry. Multiple entry
here refers to allow more than one count of address ranges for MEMORY
region type. This helps to add support for SoC's like OcteonTX/TX2
where every peripheral is on the PCI bus.
config PCI_SRIOV
bool "Enable Single Root I/O Virtualization support for PCI"
depends on PCI || DM_PCI
default n
help
Say Y here if you want to enable PCI Single Root I/O Virtualization
capability support. This helps to enumerate Virtual Function devices
if available on a PCI Physical Function device and probe for
applicable drivers.
config PCI_ARID
bool "Enable Alternate Routing-ID support for PCI"
depends on PCI || DM_PCI
default n
help
Say Y here if you want to enable Alternate Routing-ID capability
support on PCI devices. This helps to skip some devices in BDF
scan that are not present.

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 PCIE_FSL
bool "FSL PowerPC PCIe support"
depends on DM_PCI
help
Say Y here if you want to enable PCIe controller support on FSL
PowerPC MPC85xx, MPC86xx, B series, P series and T series SoCs.
This driver does not support SRIO_PCIE_BOOT feature.
config PCI_MPC85XX
bool "MPC85XX PowerPC PCI support"
depends on DM_PCI
help
Say Y here if you want to enable PCI controller support on FSL
PowerPC MPC85xx SoC.
config PCI_RCAR_GEN2
bool "Renesas RCar Gen2 PCIe driver"
depends on DM_PCI
depends on RCAR_32
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_RCAR_GEN3
bool "Renesas RCar Gen3 PCIe driver"
depends on DM_PCI
depends on RCAR_GEN3
help
Say Y here if you want to enable PCIe controller support on
Renesas RCar Gen3 SoCs.
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 ARCH_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_OCTEONTX
bool "OcteonTX PCI support"
depends on (ARCH_OCTEONTX || ARCH_OCTEONTX2)
help
Enable support for the OcteonTX/TX2 SoC family ECAM/PEM controllers.
These controllers provide PCI configuration access to all on-board
peripherals so it should only be disabled for testing purposes
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

configured to Root Complex mode by clearing the corresponding bit of
RCW[HOST_AGT_PEX].
config PCI_IOMMU_EXTRA_MAPPINGS
bool "Support for specifying extra IOMMU mappings for PCI"
depends on PCIE_LAYERSCAPE_RC
help
Enable support for specifying extra IOMMU mappings for PCI
controllers through a special env var called "pci_iommu_extra" or
through a device tree property named "pci-iommu-extra" placed in
the node describing the PCI controller.

and PCI hot-plug scenarios. More documentation can be found under:
arch/arm/cpu/armv8/fsl-layerscape/doc/README.pci_iommu_extra
config PCIE_LAYERSCAPE_EP
bool "Layerscape PCIe Endpoint mode support"
