 229  * BOOL AMD_CB_ManualBUIDSwapList(u8 Node, u8 Link, u8 **List)
 230  * Description:
 231  *      This routine is called every time a non-coherent chain is processed.
 232  *      BUID assignment may be controlled explicitly on a non-coherent chain. Provide a
 233  *      swap list. The first part of the list controls the BUID assignment and the
 234  *      second part of the list provides the device to device linking.  Device orientation
 235  *      can be detected automatically, or explicitly.  See documentation for more details.
 236  *
 237  *      Automatic non-coherent init assigns BUIDs starting at 1 and incrementing sequentially
 238  *      based on each device's unit count.
 239  *
 240  * Parameters:
 241  *      @param[in]  node   = The node on which this chain is located
 242  *      @param[in]  link   = The link on the host for this chain
 243  *      @param[out] List   = supply a pointer to a list
