Which is not okay. 'External' to what? 'untrusted' has been carefully
chosen by the meaning of it.
What external does mean for M.2. WWAN card in my laptop? It's in ACPI
tables, but I can replace it.
This is only one example. Or if firmware of some device is altered,
and it's internal (whatever it means) is it trusted or not?
So, please leave it as is (I mean name).
