| 207 | * This routine is called every time a non-coherent chain is processed. |
| 208 | * BUID assignment may be controlled explicitly on a non-coherent chain. Provide a |
| 209 | * swap list. The first part of the list controls the BUID assignment and the |
| 210 | * second part of the list provides the device to device linking. Device orientation |
| 211 | * can be detected automatically, or explicitly. See documentation for more details. |
| 212 | * |
| 213 | * Automatic non-coherent init assigns BUIDs starting at 1 and incrementing sequentially |
| 214 | * based on each device's unit count. |
| 215 | * |
| 216 | * Parameters: |
