Not sure I understand your request correctly: the TPM commands are
already available in the sandbox (I don't see what I could add), I just
extended the current set of commands.

However, even with these commands, we won't be able to test them in a
sandbox unless with an actual device.

I probably miss something, can you explain a bit more what you would
like?

Thank you,
Miquèl
