+	  This option adds the workaround for ARM Cortex-A510 erratum 2038923.
+
+	  Affected Cortex-A510 core might cause an inconsistent view on whether trace is
+	  prohibited within the CPU. As a result, the trace buffer or trace buffer state
+	  might be corrupted. This happens after TRBE buffer has been enabled by setting
+	  TRBLIMITR_EL1.E, followed by just a single context synchronization event before
+	  execution changes from a context, in which trace is prohibited to one where it
+	  isn't, or vice versa. In these mentioned conditions, the view of whether trace
+	  is prohibited is inconsistent between parts of the CPU, and the trace buffer or
+	  the trace buffer state might be corrupted.
+
+	  Work around this in the driver by preventing an inconsistent view of whether the
+	  trace is prohibited or not based on TRBLIMITR_EL1.E by immediately following a
+	  change to TRBLIMITR_EL1.E with at least one ISB instruction before an ERET, or
+	  two ISB instructions if no ERET is to take place.

+
+	  Affected Cortex-A510 core might cause trace data corruption, when being written
+	  into the memory. Effectively TRBE is broken and hence cannot be used to capture
+	  trace data.
+
+	  Work around this problem in the driver by just preventing TRBE initialization on
+	  affected cpus. The firmware must have disabled the access to TRBE for the kernel
+	  on such implementations. This will cover the kernel for any firmware that doesn't
+	  do this already.
