21 * 0x00946C00.
22 * - Set the stack at the end of the free area section, at 0x00946BB8.
23 * - The BOOT ROM loads what they consider the firmware image
24 * which consists of a 4K header in front of us that contains the IVT, DCD
25 * and some padding thus 'our' max size is really 0x00946BB8 - 0x00911000.
26 * 64KB is more then enough for the SPL.
