Simply because the hardware I have (Developerbox) doesn't provide
enough flash space (as per current memory map) for this fTPM driver to
be loaded as early TA along with OP-TEE binary. So I can't get any
further point than sanity probe failure check for which I think a
tested-by won't be appropriate.
