Thanks Stefan.

In general, it looks okay to me.  Since this depends on a qemu change,
though, I'd like to see a qemu/kvm maintaner ack (or the dependent
changes committed in qemu) before committing to SeaBIOS.

Some minor nits:

Patch 4:

This looks stale.

Patch 5:

I'd prefer to avoid #ifdefs - it should be possible to do something

sha1_calc(...) {
         return tpm_sha1_calc(...);
    return sha1(...);

Finally, can you briefly describe what services that require TPM
support will now be available to end-users with this series?
