[coreboot] tpm api merge

[Alexander Couzens]

Hi,

I'm looking at a huge tpm merge commit. +625, -748

So the question how can we merge this? As long we don't have further
testing, it's hard to decide. We won't catch all bugs. May be
chromeos have a tpm testing?

And also reorganize the commit into smaller ones are very hard and I
think it's not the effort worthy. Because merging two apis into one
is a big thing.

The only other way I can imagine merge 
I don't know how easy it is, having 3 apis lying in the tree.
The 2 "old" apis and the new merged one. Extending the new api until
it's working.

Can we freeze the tpm apis for now? It would give zaolin more time to
fix the problems and give the reviewer also more time to look over?!

Best,
lynxis
