16 * - IMX7D/S OCRAM free area RAM (OCRAM) is from 0x00910000 to
18 * - Set the stack at the end of the free area section, at 0x00946BB8.
19 * - 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 0x00946BB8 - 0x00911000.
22 * 64KB is more then enough for the SPL.
24 #define CONFIG_SPL_MAX_SIZE 0x10000
25 #define CONFIG_SPL_STACK 0x00946BB8
27 * Pad SPL to 68KB (4KB header + 64KB max size). This allows to write the
28 * SPL/U-Boot combination generated with u-boot-with-spl.imx directly to a
29 * boot media (given that boot media specific offset is configured properly).
