Is there anything which is actually Xen specific about the driver in
tpm.[ch]? Would it be better to just probe for it, perhaps gates by
a Kconfig option which enables TPM support.
I also think the probing should be done. That code can also be
recycled from what I posted earlier. It's gated by a Kconfig option, so it 
doesn't
fill up the 128k ROM.

Agree, I will do it ASAP.
I reposted v9 of my series of patches. I will probably post v10 today.
Please try that one then since these patches should cover Xen, QEMU (using a
driver that only I can test at the moment), and to some extent bare metal
system.

Great!  Could you also archive v10 to your github?
then I can also test it and go through these source code.

I put it here now:
