+	 * ISO clients(EQOS) that need ordering should use PCFIFO ordering
+	 *     and bypass ROC ordering by using FORCE_NON_COHERENT path.
+	 * FORCE_NON_COHERENT/FORCE_COHERENT config take precedence
+	 *     over SMMU attributes.
+	 * Force all Normal memory transactions from ISO and non-ISO to be
+	 *     non-coherent(bypass ROC, avoid cache snoop to avoid perf hit).
+	 * Force the SO_DEV transactions from ordered ISO clients(EQOS) to
+	 *     non-coherent path and enable MC PCFIFO interlock for ordering.
+	 * Force the SO_DEV transactions from ordered non-ISO clients (PCIe,
+	 *     XUSB, SATA) to coherent so that the transactions are
+	 *     ordered by ROC.
+	 * PCFIFO ensure write ordering.
+	 * Read after Write ordering is maintained/enforced by MC clients.
+	 * Clients that need PCIe type write ordering must
+	 *     go through ROC ordering.
+	 * Ordering enable for Read clients is not necessary.
+	 * R5's and A9 would get necessary ordering from AXI and
+	 *     don't need ROC ordering enable:
+	 *     - MMIO ordering is through dev mapping and MMIO
+	 *       accesses bypass SMMU.
+	 *     - Normal memory is accessed through SMMU and ordering is
+	 *       ensured by client and AXI.
+	 *     - Ack point for Normal memory is WCAM in MC.
+	 *     - MMIO's can be early acked and AXI ensures dev memory ordering,
+	 *       Client ensures read/write direction change ordering.
+	 *     - See Bug 200312466 for more details.
 	 *
-	 * Change AXID_OVERRIDE/AXID_OVERRIDE_SO_DEV only for some clients
-	 * whose AXI IDs we know and trust.
