| 10 | Xillybus is a generic interface for peripherals designed on |
| 11 | programmable logic (FPGA). The driver probes the hardware for |
| 12 | its capabilities, and creates device files accordingly. |
| 13 | |
| 14 | If unsure, say N. |

| 21 | help |
| 22 | Set to M if you want Xillybus to use PCI Express for communicating |
| 23 | with the FPGA. |

| 28 | help |
| 29 | Set to M if you want Xillybus to find its resources from the |
| 30 | Open Firmware Flattened Device Tree. If the target is an embedded |
| 31 | system, say M. |
