| 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. | |

| 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. | |

21 | config 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. | |

31 | config PCI_TEGRA |
| 32 | bool "Tegra PCI support" | |
| 33 | depends on TEGRA | |
| 34 | help | |
| 35 | Enable support for the PCIe controller found on some generations of | |
| 36 | Tegra. Tegra20 has 2 root ports with a total of 4 lanes, Tegra30 has | |
| 37 | 3 root ports with a total of 6 lanes and Tegra124 has 2 root ports | |
| 38 | with a total of 5 lanes. Some boards require this for Ethernet | |
| 39 | support to work (e.g. beaver, jetson-tk1). | |
