My true and honest answer is that I cannot recall. Not sure even if it
was like when the driver was still out-of-tree implementation. This
would back to 2016 :-)

But we don't need to dig the exact answr because

➜  linux-tpmdd (next) ✔ git --no-pager grep -e BSD --and \( -e SPDX \)  -- "arch/*.[Sc]"
arch/arm64/lib/tishift.S:/* SPDX-License-Identifier: (GPL-2.0 OR BSD-3-Clause)

Oh darn, I guess this implies that my hands are tied :-) I'll gladly
implement the change.
