> Just the verstage portion of coreboot is run again. It initializes eSPI and TPM then exits early. […]

Ah, so there's hardware init because verstage runs before the bootblock,
I guess.

If the TPM is reset, doesn't that imply, for instance, that all measure-
ments are lost just when the OS idled? or is S0i3 only entered on explicit
request?
