menu "PCI" config DM_PCI bool "Enable driver mode 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_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 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). endmenu
