I have not yet a ROM version since the board variant with flash has not 
yet arrived.  I may post an untested version tomorrow.  The work area 
function is quite simple:

#include <bsp/linker-symbols.h>
#include <bsp/bootcard.h>

void bsp_get_work_area(
   void   **work_area_start,
   size_t  *work_area_size,
   void   **heap_start,
   size_t  *heap_size
   *work_area_start = bsp_section_work_area_start;
   *work_area_size = (size_t) bsp_section_work_area_size;
