| 15 | * see figure 6-22 in i.MX 7Dual/Solo Reference manuals: |
| 16 | * - IMX7D/S OCRAM free area RAM (OCRAM) is from 0x00910000 to |
| 17 | * 0x00946C00. |
| 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 |
| Matthias Schiffer | bc95990 | 2021-09-28 13:40:52 +0200 | [diff] [blame] | 21 | * and some padding. However, the manual also states that the ROM uses the |
| 22 | * OCRAM_EPCD and OCRAM_PXP areas for itself. While the SPL is free to use |
| 23 | * this range for stack and malloc, the SPL itself must fit below 0x920000, |
| 24 | * or the image will be truncated in at least some boot modes like USB SDP. |
| 25 | * Thus our max size is really 0x00920000 - 0x00912000. If necessary, |
| 26 | * CONFIG_SPL_TEXT_BASE could be moved to 0x00911000 to gain 4KB of space |
| 27 | * for the SPL, but 56KB should be more than enough for the SPL. |
