+         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.
