1menu "PCI" 2 3config DM_PCI 4 bool "Enable driver mode for PCI" 5 depends on DM 6 help 7 Use driver model for PCI. Driver model is the new method for 8 orgnising devices in U-Boot. For PCI, driver model keeps track of 9 available PCI devices, allows scanning of PCI buses and provides 10 device configuration support. 11 12config DM_PCI_COMPAT 13 bool "Enable compatible functions for PCI" 14 depends on DM_PCI 15 help 16 Enable compatibility functions for PCI so that old code can be used 17 with CONFIG_DM_PCI enabled. This should be used as an interim 18 measure when porting a board to use driver model for PCI. Once the 19 board is fully supported, this option should be disabled. 20 21config PCI_SANDBOX 22 bool "Sandbox PCI support" 23 depends on SANDBOX && DM_PCI 24 help 25 Support PCI on sandbox, as an emulated bus. This permits testing of 26 PCI feature such as bus scanning, device configuration and device 27 access. The available (emulated) devices are defined statically in 28 the device tree but the normal PCI scan technique is used to find 29 then. 30 31config PCI_TEGRA 32 bool "Tegra PCI support" 33 depends on TEGRA 34 depends on (TEGRA186 && POWER_DOMAIN) || (!TEGRA186) 35 help 36 Enable support for the PCIe controller found on some generations of 37 Tegra. Tegra20 has 2 root ports with a total of 4 lanes, Tegra30 has 38 3 root ports with a total of 6 lanes and Tegra124 has 2 root ports 39 with a total of 5 lanes. Some boards require this for Ethernet 40 support to work (e.g. beaver, jetson-tk1). 41 42endmenu 43
