15*88c307d1STim Harvey  * see Figure 8-3 in IMX6DQ/IMX6SDL Reference manuals:
16*88c307d1STim Harvey  *  - IMX6SDL OCRAM (IRAM) is from 0x00907000 to 0x0091FFFF
17*88c307d1STim Harvey  *  - IMX6DQ has 2x IRAM of IMX6SDL but we intend to support IMX6SDL as well
18*88c307d1STim Harvey  *  - BOOT ROM stack is at 0x0091FFB8
19*88c307d1STim Harvey  *  - if icache/dcache is enabled (eFuse/strapping controlled) then the
20*88c307d1STim Harvey  *    IMX BOOT ROM will setup MMU table at 0x00918000, therefore we need to
21*88c307d1STim Harvey  *    fit between 0x00907000 and 0x00918000.
22*88c307d1STim Harvey  *  - Additionally the BOOT ROM loads what they consider the firmware image
23*88c307d1STim Harvey  *    which consists of a 4K header in front of us that contains the IVT, DCD
24*88c307d1STim Harvey  *    and some padding thus 'our' max size is really 0x00908000 - 0x00918000
25*88c307d1STim Harvey  *    or 64KB
