 *   All STM32 architectures must provide the following entry point.  This entry point
 *   is called early in the intitialization -- after all memory has been configured
 *   and mapped but before any devices have been initialized.

 *   called immediately after up_initialize() is called and just before the

 *   may be used, for example, to initialize board-specific device drivers.
