* 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
