Hi,

I have a working PoC for boot-time initialization of vtpm inside
tpm_vtpm_proxy. ATM, it uses the Linux firmware interface to load a ELF
binary for the vtpm, and delivers a communication end for the helper
process.

It is a great feature with the current narrow scope for continuous
integration. Obviously the scope could be later on extended to e.g.
from unencrypted plain text to a vTPM living inside SGX enclave.

I could send an RFC of this, if there is wider interest for the
topic.

BR, Jarkko
