This option adds a workaround for ARM Cortex-A55 Erratum 1024718.

Affected Cortex-A55 cores (r0p0, r0p1, r1p0) could cause incorrect
update of the hardware dirty bit when the DBM/AP bits are updated
without a break-before-make. The workaround is to disable the usage
of hardware DBM locally on the affected cores. CPUs not affected by
this erratum will continue to use the feature.

If unsure, say Y.
