Trustworthy in what sense? That they are delivering on spec, or that they aren't stealing your IP?
For the prior, I imagine going there and observing QC procedures is the only hope. For the latter, I imagine it involves keeping discrete critical components isolated -- firmware from silicon (and beyond), using different factories so that neither independently has a functional device.
