| * - IMX6SDL OCRAM (IRAM) is from 0x00907000 to 0x0091FFFF |
| * - 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 |
