Help text

This option enables the workaround for: - Cortex-A17 852423: Execution of a sequence of instructions might lead to either a data corruption or a CPU deadlock. Not fixed in any Cortex-A17 cores yet. This is identical to Cortex-A12 erratum 852422. It is a separate config option from the A12 erratum due to the way errata are checked for and handled.
