Cortex-A510: Completion of affected memory accesses might not be guaranteed by completion of a TLBI

This option adds a workaround for ARM Cortex-A510 erratum #2441009.

Under very rare circumstances, affected Cortex-A510 CPUs
may not handle a race between a break-before-make sequence on one
CPU, and another CPU accessing the same page. This could allow a
store to a page that has been unmapped.

Work around this by adding the affected CPUs to the list that needs
TLB sequences to be done twice.

If unsure, say Y.
