Hi,
I accumulated a series of patch doing some TPM code cleanup while
doing review. I removed some dead code, simplified other parts, and
tried to isolate implementation of the backend and frontend by using a
new TPMIf interface. I solved a few issues, and added some FIXME for
what should be tackled. Finally, I implemented a simple CRB device
(tpm 2.0) that is work in progress for now - it works fine with
passthrough, but swtpm/libtpms with win10 has some issues that need
more investigations.
seabios CRB support is required for TPM 2.0 & emulation
