+          This options enables the workaround for the 364296 ARM1136
+          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
+          is not affected.
