In fact, the SPL boot path for OP-TEE doesn't use this function. That's
intentional.
Here's what I suggest:
- Remove OPTEE_TZDRAM_BASE and _SIZE
There is some legacy here, board/warp7and board/technexion/pico-imx7d.
it is not possible, it is used for U-Boot proper on other platforms
board/warp7/warp7.c:38: gd->ram_size -= CONFIG_OPTEE_TZDRAM_SIZE;
board/warp7/warp7.c:122: optee_start = optee_end -
CONFIG_OPTEE_TZDRAM_SIZE;
board/technexion/pico-imx7d/pico-imx7d.c:56: gd->ram_size -=
CONFIG_OPTEE_TZDRAM_SIZE;
include/configs/mx7_common.h:52:#if (CONFIG_OPTEE_TZDRAM_SIZE != 0)
I have an idea how to work around that.
This is what I had in mind [1]. With this, optee_verify_bootm_image() is
just three or four checks.
I propose that code which would have been under CONFIG_OPTEE_IMAGE, is
instead moved under CONFIG_BOOTM_OPTEE. Thus there's no need for
CONFIG_OPTEE_IMAGE in the first place, and all the other changes make sense.
