| 245 | * BOOL AMD_CB_ManualBUIDSwapList(u8 Node, u8 Link, u8 **List) |
| 246 | * Description: |
| 247 | * This routine is called every time a non-coherent chain is processed. |
| 248 | * BUID assignment may be controlled explicitly on a non-coherent chain. Provide a |
| 249 | * swap list. The first part of the list controls the BUID assignment and the |
| 250 | * second part of the list provides the device to device linking. Device orientation |
| 251 | * can be detected automatically, or explicitly. See documentation for more details. |
| 252 | * |
| 253 | * Automatic non-coherent init assigns BUIDs starting at 1 and incrementing sequentially |
| 254 | * based on each device's unit count. |
| 255 | * |
| 256 | * Parameters: |
Martin Roth | c3fde7e | 2014-12-29 22:13:37 -0700 | [diff] [blame] | 257 | * @param[in] node = The node on which this chain is located |
| 258 | * @param[in] link = The link on the host for this chain |
| 259 | * @param[out] List = supply a pointer to a list |
