+--------------------------------------------------------------------------+
| If the BSP wants to dynamically allocate the memory for the C Library heap
| (malloc) and/or be able to extend the heap, then this routine must be
| functional. RTEMS newlib suppport has an implementation of malloc using
| RTEMS regions => the user can do mallocs.
