Commit c7b3a7ee5351 ("optee: adjust dependencies and default values for dram") wants to skip low-level init of i.MX7 hardware in the case where OP-TEE has already run and u-boot is being run as BL33 in normal world.
Currently we check for both #ifdef CONFIG_OPTEE_TZDRAM_SIZE and #ifndef CONFIG_OPTEE to determine if lowlevel init should be skipped, however, in order to ensure non-OPTEE users never see OPTEE related defines we cannot rely on this method.
Fortunately we can use CONFIG_BOOTM_OPTEE for the same purpose. CONFIG_BOOTM_OPTEE is only relevant if you want u-boot to load OP-TEE not if u-boot has already been loaded by OP-TEE.
