 * Name: drivers_initialize
 *
 * Description:
 *   drivers_initialize will be called once during OS initialization after
 *   the basic OS services have been initialized.
 *
 *   drivers_initialize is called after the OS initialized but before the
 *   user initialization logic has been started and before the libraries
 *   have been initialized.  OS services and driver services are available.
