multi band/ out of band/ multi factor TPM TOTP codes for boot verification / increased boot verity/ assurance - puri.sm leading Free Libre Open Source Software, Hardware and Security vision

Multi factor boot authentication, making use of the TPM chip (to
whatever extent you might consider that worthwhile or otherwise),
generation of a QR code and a mobile phone app for external (to your
laptop/ computer) "verification" of bootup hash values, doing so all
in free libre and open source software (of course), is now in sight:

Ideally, we'd actually have our own seL4 or other small sized kernel
inside the Intel ME, so we could make full use of it; beginnings:

Next, we need a libre hardware/ auditable "free/libre" hardware/ chip
for ethernet and/ or wireless, as that'd be my first port of call if
I were with intent and dollar$ to undermine "generally available
hardware" in such a way that my rogue infiltration packet opened a
hardware backdoor (on generally available hardware).
