Will need to adapt image signing tools to use a scheme like the following: https://developers.yubico.com/PIV/Guides/Android_code_signing.html

I looked into this briefly, and wrote down my findings at https://gitlab.com/calyxos/calyxos/wikis/Offline-signing

TL;DR:

Some AOSP scripts will need slight modifications
Need a signapk which supports keys stored on dedicated hardware
Need to write an external program that's called by avbtool to sign things using keys stored on dedicated hardware.
