	  It is typical whenever OP-TEE OS is loaded before U-Boot proper that
	  it modifies the FDT passed to U-Boot proper to add reserved-memory
	  nodes for the RAM it just reserved for itself.

	  U-Boot must copy those reserved-nodes in the FDT for the next OS to
	  boot.

	  Failing to do so will incur random crashes or device reboots once the
	  next OS is running.

	  This makes sure that whenever TEE is present in the environment,
	  meaning a TEE OS will be part of the boot flow, the copy made by the
	  OP-TEE lib will happen.

config OPTEE_IMAGE

	  The bootflow is BootROM -> u-boot -> OPTEE -> Linux in this case.
