- * - IMX6DQ has 2x IRAM of IMX6SDL but we intend to support IMX6SDL as well
- * - BOOT ROM stack is at 0x0091FFB8
- * - if icache/dcache is enabled (eFuse/strapping controlled) then the
- * IMX BOOT ROM will setup MMU table at 0x00918000, therefore we need to
- * fit between 0x00907000 and 0x00918000.
- * - Additionally the BOOT ROM loads what they consider the firmware image
- * which consists of a 4K header in front of us that contains the IVT, DCD
- * and some padding thus 'our' max size is really 0x00908000 - 0x00918000
- * or 64KB
