| 15 | Use driver model for PCI. Driver model is the new method for |
| 16 | orgnising devices in U-Boot. For PCI, driver model keeps track of |
| 17 | available PCI devices, allows scanning of PCI buses and provides |
| 18 | device configuration support. |

| 25 | with CONFIG_DM_PCI enabled. This should be used as an interim |
| 26 | measure when porting a board to use driver model for PCI. Once the |
