+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
+       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).
