Joakim,
Please help to answer below query from Michael regarding licensing concerns for using Global Platform specs content in OP-TEE.

Ard,
I think it depends on the license behind the click through.
The fact that there is another .h file with the same content under a BSD license is good data point. However, that other .h file does not reference the spec with the click through license, so it is not clear where the define values come from. I looked at the root of that tree, and it has a Readme.md that has a link to a Notice.md that has a link to a Notice.md in another repository that then has a link to the same specs that require the click through.
https://github.com/OP-TEE/optee_client/blob/master/README.md https://github.com/OP-TEE/optee_client/blob/master/Notice.md https://github.com/OP-TEE/optee_os/blob/master/Notice.md https://globalplatform.org/specs-library/
Can you explain how this other project is using spec content that requires a click through license.
Thanks,
Mike

Hi Ard,
The initial content is only from the TEE Client API
Specification.
I noticed that there is an errata to that spec as
well. Does this
content follow the errata?
Yes.
I also noticed that the specifications require the
acceptance of
an additional license to view the contents. Is
there a version of
the content for this include file available that
does not require
the acceptance of an additional license?
Yes, following is another version of the content for
this include file:
TEE/optee_client/blob/master/public/tee_client_api.h#L16 3
Thanks Sumit.
Mike,
are you saying this content should not be [click through] license encumbered if we want to put it into MdePkg as an industry standard?

Mike,
The header file is a bit light on content at
introduction, but as
discussed online, we can add stuff as we go for
other
use cases.
... as discussed *offline*
