  * Description:
  *   Perform architecture specific initialization
  *
+ * Input Parameters:
+ *   arg - The boardctl() argument is passed to the board_app_initialize()
+ *         implementation without modification.  The argument has no
+ *         meaning to NuttX; the meaning of the argument is a contract
+ *         between the board-specific initalization logic and the the
+ *         matching application logic.  The value cold be such things as a
+ *         mode enumeration value, a set of DIP switch switch settings, a
+ *         pointer to configuration data read from a file or serial FLASH,
+ *         or whatever you would like to do with it.  Every implementation
+ *         should accept zero/NULL as a default configuration.
+ *
+ * Returned Value:
+ *   Zero (OK) is returned on success; a negated errno value is returned on
+ *   any failure to indicate the nature of the failure.
+ *
