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.

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.

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).
