I pointed out what's missing on the sandbox.  Asking for the tests is
fine and those will be added,  but since the TPM is already working in
QEMU,  I strongly prefer doing it there.

I know you like sandbox and you are trying to promote using it for testing, 
but imho having it for the TPM is not the best of examples.  You are adding 
code emulating a really complex device.  There's *always* going to be
missing functionality (not to mention bugs). 

The EFI TCG tests will ask more and more from the TPM.  E.g there's a call for 
changing the active PCRs which we haven't implemented yet in EFI.  We'll have
to keep adding  complex features to sandbox for every patch?
QEMU and it's TPM already work and have all the functionality we'll ever need.
In fact this [1] came out from testing on QEMU.   So since QEMU and testing
is an acceptable way for testing U-Boot,  I'll resend my TPM MMIO patchset
and we can create the tests there.
