> From: Ricardo Salveti <ricardo at foundries.io>
> On the iMX7ULP uCOM board, OP-TEE uses the memory region defined by the
> maximum DRAM address minus CONFIG_OPTEE_TZDRAM_SIZE, so subtract
> CONFIG_OPTEE_TZDRAM_SIZE from the available DRAM size to avoid
> conflicts.
> Note the OPTEE boot process itself subtracts the DRAM region it
> lives in from the memory map passed to Linux.
