  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
