 *   memory have been configured but before caches have been enabled and
 *   before any devices have been initialized.

 *   called immediately after up_intitialize() is called and just before the
 *   initial application is started.  This additional initialization phase
 *   may be used, for example, to initialize board-specific device drivers.
