+ bool "Use ClearFog Base static configuration"
+ help
+ Use the ClearFog Base as the static configuration instead of the
+ default which uses the ClearFog Pro.
+
+ Runtime board detection is always attempted and used if available. The
+ static configuration is used as a fallback in cases where runtime
+ detection is disabled, is not available in hardware, or otherwise fails.
+
+ Only newer revisions of the ClearFog product line support runtime
+ detection via additional EEPROM hardware. This option enables selecting
+ the Base variant for older hardware revisions.
