* meaning to NuttX; the meaning of the argument is a contract
* between the board-specific initialization logic and 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.
