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

Comments/review welcome!
Are you going to post a v2 soon?
I was wondering if you would take the patches that you already
reviewed for the next pull request. That way v2 would be smaller.
I'll take them up to 21/42.
Tested them and it seems to work fine. I'll post later today.
Did you have any more luck with win10 and tpm2 ?
I haven't had time so far to investigate further.
The summary was that Windows refuses to talk with a TPM2/TIS device (it doesn't
even shows up in device list), while TPM2/CRB is being recognized and
communicated with. However, there are some failure with swtpm/libtpms that are
unclear, and will require more verbosity in libtpms. I plan to resume this
effort in a few weeks.
TPM1.2 + TIS seems good.
TPM 2 + CRB seems to have a problem with a key handle 0x81 00 00 01.
Stefan
Thanks
