PS2, Line 51: ## Disable Active Policy from baseboard
            : 				register "policies.active" = "{[0] = {.target=DPTF_NONE}}"
This should not be required, there is no policy defined in the baseoboard. For brya, we decided to let each variant fully define its own policies; it led to too much confusion in previous programs

Only integral degrees C are supported

This could probably be 0, DPTF does not adjust PL2 currently
