/* Common commands
*
* CMD: BOARDIOC_INIT
* DESCRIPTION: Perform one-time application initialization.
* 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
* initialization logic and the matching application logic.
* The value could 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.
* CONFIGURATION: CONFIG_BOARDCTL
* DEPENDENCIES: Board logic must provide board_app_initialize()
*
* CMD: BOARDIOC_POWEROFF
* DESCRIPTION: Power off the board
* ARG: Integer value providing power off status information
* CONFIGURATION: CONFIG_BOARDCTL_POWEROFF
* DEPENDENCIES: Board logic must provide the board_power_off() interface.
*
* CMD: BOARDIOC_RESET
* DESCRIPTION: Reset the board
* ARG: Integer value providing power off status information
* CONFIGURATION: CONFIG_BOARDCTL_RESET
* DEPENDENCIES: Board logic must provide the board_reset() interface.
*
* CMD: BOARDIOC_PM_CONTROL
* DESCRIPTION: Manage power state transition and query
* ARG: A pointer to an instance of struct boardioc_pm_ctrl_s
* CONFIGURATION: CONFIG_PM
* DEPENDENCIES: None
*
* CMD: BOARDIOC_UNIQUEID
* DESCRIPTION: Return a unique ID associated with the board (such as a
* serial number or a MAC address).
* ARG: A writable array of size CONFIG_BOARDCTL_UNIQUEID_SIZE in
* which to receive the board unique ID.
* DEPENDENCIES: Board logic must provide the board_uniqueid() interface.
*
* CMD: BOARDIOC_MKRD
* DESCRIPTION: Create a RAM disk
* ARG: Pointer to read-only instance of struct boardioc_mkrd_s.
* CONFIGURATION: CONFIG_BOARDCTL_MKRD
* DEPENDENCIES: None
*
* CMD: BOARDIOC_ROMDISK
* DESCRIPTION: Register a ROM disk
* ARG: Pointer to read-only instance of struct boardioc_romdisk_s.
* CONFIGURATION: CONFIG_BOARDCTL_ROMDISK
* DEPENDENCIES: None
*
* CMD: BOARDIOC_APP_SYMTAB
* DESCRIPTION: Select the application symbol table. This symbol table
* provides the symbol definitions exported to application
* code from application space.
* ARG: A pointer to an instance of struct boardioc_symtab_s
* CONFIGURATION: CONFIG_BOARDCTL_APP_SYMTAB
* DEPENDENCIES: None
*
* CMD: BOARDIOC_OS_SYMTAB

* the symbol definitions exported by the OS to kernel
* modules.
* ARG: A pointer to an instance of struct boardioc_symtab_s
* CONFIGURATION: CONFIG_BOARDCTL_OS_SYMTAB
* DEPENDENCIES: None
*
* CMD: BOARDIOC_BUILTINS
* DESCRIPTION: Provide the user-space list of built-in applications for
* use by BINFS in protected mode. Normally this is small
* set of globals provided by user-space logic. It provides
* name-value pairs for associating built-in application
* names with user-space entry point addresses. These
* globals are only needed for use by BINFS which executes
* built-in applications from kernel-space in PROTECTED mode.
* In the FLAT build, the user space globals are readily
* available. (BINFS is not supportable in KERNEL mode since
* user-space address have no general meaning that
* configuration).
* ARG: A pointer to an instance of struct boardioc_builtin_s
* CONFIGURATION: This BOARDIOC command is always available when
* CONFIG_BUILTIN is enabled, but does nothing unless
* CONFIG_BUILD_PROTECTED is also selected.
* DEPENDENCIES: None

* Name: boardctl
*
* Description:
* In a small embedded system, there will typically be a much greater
* interaction between application and low-level board features. The
* canonically correct to implement such interactions is by implementing a
* character driver and performing the interactions via low level ioctl
* calls. This, however, may not be practical in many cases and will lead
* to "correct" but awkward implementations.
*
* boardctl() is non-standard OS interface to alleviate the problem.
* It basically circumvents the normal device driver ioctl interlace and
* allows the application to perform direct IOCTL-like calls to the
* board-specific logic.
* It is especially useful for setting up board operational and test
* configurations.
*
* Input Parameters:
* cmd - Identifies the board command to be executed
* arg - The argument that accompanies the command. The nature of the
* argument is determined by the specific command.
*
* Returned Value:
* On success zero (OK) is returned; -1 (ERROR) is returned on failure
* with the errno variable set to indicate the nature of the failure.
