└─> ARM errata: Faulty hazard checking in the Store Buffer may lead to data corruption

This option enables the workaround for the 743622 Cortex-A9
(r2p*) 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.
