No, though the post a couple of weeks ago on this subject raised the 
interesting idea of using the custom programming capability of the crypto 
cards to implement a TPM chip (context was POWER, but z has the same 
capability).

Whether TPMs on z are waiting in the wings, I have no idea, but it's 
probably been a good 10 years since I was involved in discussions about 
TPMs on z.  The problem at the time was virtualizing them at scale.  You 
would potentially want all of your guests to have a TPM.  But since aren't 
allowed to terminate inside the hypervisor to be useful, so they must be 
outside of VM, and THAT means hardware.  Much has happened since then, so 
don't use my past experience as an indication of future performance.

Are TPMs something your software security teams are wanting on z?
