Please don't ask for that.
If somebody put a signature verification for his firmware in place, you
should first discuss the reasons and alternatives (for the particular
design in question). Sure there are alternatives to signature verifi-
cations to put some trust in hardware (like ROMs or the RO partitions
in cros devices). But removing the security checks from hardware who's
trust is designed around these checks? You'd likely end up with a sys-
tem where you have to check the flash contents with external hardware
before every boot (if it can be tampered with from the running system).
Of course you can ask for alternatives in new designs.
For yet released platforms, however, it's more feasible to ask for docu-
mentation, reproducible binaries and signatures (e.g. for fixes / reim-
