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 PCI_SANDBOX 13 bool "Sandbox PCI support" 14 depends on SANDBOX && DM_PCI 15 help 16 Support PCI on sandbox, as an emulated bus. This permits testing of 17 PCI feature such as bus scanning, device configuration and device 18 access. The available (emulated) devices are defined statically in 19 the device tree but the normal PCI scan technique is used to find 20 then. 21 22config PCI_TEGRA 23 bool "Tegra PCI support" 24 depends on TEGRA 25 help 26 Enable support for the PCIe controller found on some generations of 27 Tegra. Tegra20 has 2 root ports with a total of 4 lanes, Tegra30 has 28 3 root ports with a total of 6 lanes and Tegra124 has 2 root ports 29 with a total of 5 lanes. Some boards require this for Ethernet 30 support to work (e.g. beaver, jetson-tk1). 31 32endmenu 33
