+         The CN63XXP1 chip requires build time workarounds to
+         function reliably, select this option to enable them.  These
+         workarounds will cause a slight decrease in performance on
+         non-CN63XXP1 hardware, so it is recommended to select "n"
+         unless it is known the workarounds are needed.
