Cortex A9:errata 794073 workaround On Cortex A9 an errata can cause the processor to violate the rules for speculative fetches when the MMU is off but branch prediction has not been disabled. The workaround for this is to execute an Invalidate Entire Branch Prediction Array (BPIALL) followed by a DSB. see:http://arminfo.emea.arm.com/help/topic/com.arm.doc.uan0009d/UAN0009_cortex_a9_errata_r4.pdf for more details.
