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

26 #define CONFIG_SPL_STACK 0x0091FFB8
28 * Pad SPL to 68KB (4KB header + 64KB max size). This allows to write the
29 * SPL/U-Boot combination generated with u-boot-with-spl.imx directly to a
30 * boot media (given that boot media specific offset is configured properly).
