+	  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 keeping the reference values of affected counters
+	  to 0 thus signaling an error case. This effect is the same to firmware disabling
+	  affected counters, in which case 0 will be returned when reading the disabled
+	  counters.
