|
|
* - IMX7D/S OCRAM free area RAM (OCRAM) is from 0x00910000 to
|
|
* 0x00946C00.
|
|
* - Set the stack at the end of the free area section, at 0x00946BB8.
|
|
* - 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. However, the manual also states that the ROM uses the
|
|
* OCRAM_EPCD and OCRAM_PXP areas for itself. While the SPL is free to use
|
|
* this range for stack and malloc, the SPL itself must fit below 0x920000,
|
|
* or the image will be truncated in at least some boot modes like USB SDP.
|
|
* Thus our max size is really 0x00920000 - 0x00912000. If necessary,
|
|
* CONFIG_SPL_TEXT_BASE could be moved to 0x00911000 to gain 4KB of space
|
|
* for the SPL, but 56KB should be more than enough for the SPL.

|
* The extra padding could be removed, but this value was used historically
|
|
* based on an incorrect CONFIG_SPL_MAX_SIZE definition.
|
|
* This allows to write the SPL/U-Boot combination generated with
|
|
* u-boot-with-spl.imx directly to a boot media (given that boot media specific
