* Name: board_app_initialize
*
* Description:
* Perform architecture specific initialization
*
* CONFIG_LIB_BOARDCTL=y :
* Called from the NSH library
*
* CONFIG_BOARD_INITIALIZE=y, CONFIG_NSH_LIBRARY=y, &&
* CONFIG_LIB_BOARDCTL=n :
* Called from board_initialize().
*
* 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.
