+ * DMA addresses or DMA addresses of a scatter gather list which is
+ * dynamically created.
+ *
+ * Our hardware will refuse DDCB execution if the ATS field is not as
+ * expected. That means the DDCB execution engine in the chip knows
+ * where it expects DMA addresses within the ASIV part of the DDCB and
+ * will check that against the ATS field definition. Any invalid or
