+          r0p2 erratum (possible cache data corruption with
+          hit-under-miss enabled). It sets the undocumented bit 31 in
+          the auxiliary control register and the FI bit in the control
+          register, thus disabling hit-under-miss without putting the
+          processor into full low interrupt latency mode. ARM11MPCore

+          affecting Cortex-A9 MPCore with two or more processors (all
+          current revisions). Under certain timing circumstances, a data
+          cache line maintenance operation by MVA targeting an Inner
+          Shareable memory region may fail to proceed up to either the
+          Point of Coherency or to the Point of Unification of the
+          system. This workaround adds a DSB instruction before the
+          relevant cache maintenance functions and sets a specific bit
+          in the diagnostic control register of the SCU.
