* see Figure 8-3 in IMX6DQ/IMX6SDL Reference manuals:
* - 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
