NAK = the OP-TEE nodes are ADDED by the OP-TEE firmware

when SPL is running the OP-TEE firmware is not running and the OP-TEE 
driver is not probed

=> this nodes are not required

This node should be present ONLY for backyard compatibility (STM32IMAGE 
support in U-Boot trusted boot)


regards


Patrick
