Description: ARM errata: Processor deadlock when a false hazard is created

More info: This option enables the workaround for the 458693 Cortex-A8 (r2p0) erratum. For very specific sequences of memory operations, it is possible for a hazard condition intended for a cache line to instead be incorrectly associated with a different cache line. This false hazard might then cause a processor deadlock. The workaround enables the L1 caching of the NEON accesses and disables the PLD instruction in the ACTLR register. Note that setting specific bits in the ACTLR register may not be available in non-secure mode.
