| 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). |
