| 15 | * see Figure 8-3 in IMX6DQ/IMX6SDL Reference manuals: | |
| 16 | * - IMX6SDL OCRAM (IRAM) is from 0x00907000 to 0x0091FFFF | |
| 17 | * - IMX6DQ has 2x IRAM of IMX6SDL but we intend to support IMX6SDL as well | |
| 18 | * - BOOT ROM stack is at 0x0091FFB8 | |
| 19 | * - if icache/dcache is enabled (eFuse/strapping controlled) then the | |
| 20 | * IMX BOOT ROM will setup MMU table at 0x00918000, therefore we need to | |
| 21 | * fit between 0x00907000 and 0x00918000. | |
| 22 | * - Additionally the BOOT ROM loads what they consider the firmware image | |
| 23 | * which consists of a 4K header in front of us that contains the IVT, DCD | |
| 24 | * and some padding thus 'our' max size is really 0x00908000 - 0x00918000 | |
| 25 | * or 64KB | |
