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
