+          This option enables the workaround for the 720789 Cortex-A9 (prior to
+          r2p0) erratum. A faulty ASID can be sent to the other CPUs for the
+          broadcasted CP15 TLB maintenance operations TLBIASIDIS and TLBIMVAIS.
+          As a consequence of this erratum, some TLB entries which should be
+          invalidated are not, resulting in an incoherency in the system page
+          tables. The workaround changes the TLB flushing routines to invalidate
+          entries regardless of the ASID.
