|
| If the BSP wants to dynamically allocate the memory for the C Library heap
|
| 5 |
|
|
| (malloc) and/or be able to extend the heap, then this routine must be
|
| 6 |
|
|
| functional. RTEMS newlib suppport has an implementation of malloc using
|
| 7 |
|
|
| RTEMS regions => the user can do mallocs.
