Set specific bootrom version file in 000000000000.cfg

Hi,

Is it possible to set a specific Bootrom (for older models which still use a seperate bootrom file) within the 000000000000.cfg master configuration file?

I know this is currently possible for a application version like:

<APPLICATION_SPIP300 APP_FILE_PATH_SPIP300="sip_213.ld"/>

But I can't find a option for the bootrom version, is this feature available?

Best regards,

Ivo
