+	 *     DesignWare core version 4.90A has this strange design issue
+	 * where the 'TD' bit in the Control register-1 of the ATU outbound
+	 * region acts like an override for the ECRC setting i.e. the presence
+	 * of TLP Digest(ECRC) in the outgoing TLPs is solely determined by
+	 * this bit. This is contrary to the PCIe spec which says that the
+	 * enablement of the ECRC is solely determined by the AER registers.
+	 *     Because of this, even when the ECRC is enabled through AER
+	 * registers, the transactions going through ATU won't have TLP Digest
+	 * as there is no way the AER sub-system could program the TD bit which
+	 * is specific to DsignWare core.
+	 *    The best way to handle this scenario is to program the TD bit
+	 * always. It affects only the traffic from root port to downstream
+	 * devices.
+	 * At this point,
+	 *     When ECRC is enabled in AER registers, everything works
+	 * normally
+	 *     When ECRC is NOT enabled in AER registers, then,
+	 * on Root Port:- TLP Digest (DWord size) gets appended to each packet
+	 *                even through it is not required. Since downstream
+	 *                TLPs are mostly for configuration accesses and BAR
+	 *                accesses, they are not in critical path and won't
+	 *                have much negative effect on the performance.
+	 * on End Point:- TLP Digest is received for some/all the packets coming
+	 *                from the root port. TLP Digest is ignored because,
+	 *                as per the PCIe Spec r5.0 v1.0 section 2.2.3 "TLP Digest Rules",
+	 *                when an endpoint receives TLP Digest when its
+	 *                ECRC check functionality is disabled in AER registers,
+	 *                received TLP Digest is just ignored.
+	 * Since there is no issue or error reported either side, best way to
+	 * handle the scenario is to program TD bit by default.
