+        bool "ARM errata: Faulty hazard checking in the Store Buffer may lead to data corruption"
+        depends on CPU_V7
+        help
+          This option enables the workaround for the 743622 Cortex-A9
+          (r2p0..r2p2) erratum. Under very rare conditions, a faulty
+          optimisation in the Cortex-A9 Store Buffer may lead to data
+          corruption. This workaround sets a specific bit in the diagnostic
+          register of the Cortex-A9 which disables the Store Buffer
+          optimisation, preventing the defect from occurring. This has no
+          visible impact on the overall performance or power consumption of the
+          processor.
