Is this something true of all OP-TEE? All OP-TEE on ARMv7? All OP-TEE on i.MX7? I'm asking since currently this hook is done the exact same way on a few other i.MX7 boards, and nowhere else. That says to me we should probably move this hook up somewhere, perhaps to imx_ddr_size() and poke the boards that aren't using that today to use it. -- Tom
