-config ARM_ERRATA_720789

- bool "ARM errata: TLBIASIDIS and TLBIMVAIS operations can broadcast a faulty ASID"

- depends on CPU_V7 && SMP

- help

- 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.
