+ help
+ This option adds the workaround for ARM Cortex-A510 erratum 2457168.
+
+ The AMU counter AMEVCNTR01 (constant counter) should increment at the same rate
+ as the system counter. On affected Cortex-A510 cores AMEVCNTR01 increments
+ incorrectly giving a significantly higher output value.
+
+ Work around this problem by returning 0 when reading the affected counter in
+ key locations that results in disabling all users of this counter. This effect
+ is the same to firmware disabling affected counters.
+
+ If unsure, say Y.
