Since this UPD is set to 1 by default and devicetree options are 0 by default this change will end up disabling PTM for all ports unless it is explicitly enabled in the devicetree.  I assume that is not what was intended so I inverted the option to allow only disabling for particular ports: https://review.coreboot.org/c/coreboot/+/46856
