+         This option enables the workaround for the 751472 Cortex-A9 (prior
+         to r3p0) erratum. An interrupted ICIALLUIS operation may prevent the
+         completion of a following broadcasted operation if the second

+         potentially leading to corrupted entries in the cache or TLB.

+         This option enables the workaround for the 753970 PL310 (r3p0) erratum.
+
+         Under some condition the effect of cache sync operation on
+         the store buffer still remains when the operation completes.
+         This means that the store buffer is always asked to drain and
+         this prevents it from merging any further writes. The workaround
+         is to replace the normal offset of cache sync operation (0x730)
+         by another offset targeting an unmapped PL310 register 0x740.
+         This has the same effect as the cache sync operation: store buffer
+         drain and waiting for all buffers empty.
