* NAME: bsp_start_default - BSP initialization function

* DESCRIPTION:
* This function is called before RTEMS is initialized and used
* adjust the kernel's configuration.
*
* This function also configures the CPU's memory protection unit.
*
* RESTRICTIONS/LIMITATIONS:
* Since RTEMS is not configured, no RTEMS functions can be called.
