+	help
+	  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
+	  operation is received by a CPU before the ICIALLUIS has completed,
+	  potentially leading to corrupted entries in the cache or TLB.

+config ARM_ERRATA_753970
+	bool "ARM errata: cache sync operation may be faulty"
+	depends on CACHE_PL310
+	help
+	  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.
