| * BOOL AMD_CB_ManualBUIDSwapList(u8 Node, u8 Link, u8 **List) |
| * Description: |
| * This routine is called every time a non-coherent chain is processed. |
| * BUID assignment may be controlled explicitly on a non-coherent chain. Provide a |
| * swap list. The first part of the list controls the BUID assignment and the |
| * second part of the list provides the device to device linking. Device orientation |
| * can be detected automatically, or explicitly. See documentation for more details. |
| * |
| * Automatic non-coherent init assigns BUIDs starting at 1 and incrementing sequentially |
| * based on each device's unit count. |
| * |
| * Parameters: |
| * @param[in] u8 node = The node on which this chain is located |
| * @param[in] u8 link = The link on the host for this chain |
| * @param[out] u8** list = supply a pointer to a list |
| * @param[out] BOOL result = true to use a manual list |
| * false to initialize the link automatically |
