This option defaults to 0.
- ``DRTM_SUPPORT``: Boolean flag to enable support for Dynamic Root of Trust
for Measurement (DRTM). This feature has trust dependency on BL31 for taking
the measurements and recording them as per `PSA DRTM specification`_. For
platforms which use BL2 to load/authenticate BL31 ``TRUSTED_BOARD_BOOT`` can
be used and for the platforms which use ``RESET_TO_BL31`` platform owners
should have mechanism to authenticate BL31.
This option defaults to 0.
- ``NON_TRUSTED_WORLD_KEY``: This option is used when ``GENERATE_COT=1``. It
specifies the file that contains the Non-Trusted World private key in PEM
format. If ``SAVE_KEYS=1``, this file name will be used to save the key.
