ARM errata: A12: DMB NSHST/ISHST mixed ... might cause deadlock
This option enables the workaround for the 825619 Cortex-A12
(all revs) erratum. Within rare timing constraints, executing a
DMB NSHST or DMB ISHST instruction followed by a mix of Cacheable
and Device/Strongly-Ordered loads and stores might cause deadlock
