19  *  - Set the stack at the end of the free area section, at 0x00946BB8.
20  *  - The BOOT ROM loads what they consider the firmware image
21  *    which consists of a 4K header in front of us that contains the IVT, DCD
22  *    and some padding thus 'our' max size is really 0x00946BB8 - 0x00911000.
23  *    64KB is more then enough for the SPL.
