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.

Re: [PATCH v2 1/2] MdePkg/IndustryStandard: Add Global Plaform header file

[Kinney, Michael D]

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?

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?

Thanks,

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?

Re: [PATCH v2 1/2] MdePkg/IndustryStandard: Add Global Plaform header file

[Kinney, Michael D]

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

Please help to answer below query from Michael regarding licensing

Please share your views on this and if we could include content from
Global Platform spec into MdePkg as an industry standard.

Having had a discussion about this, the bit that concerns us the most
is the export restrictions clause of the click-through license which
contains the very unfortunate part "or any product complying with the
Specification.".

Someone must have thought this interface defines cryptography, rather
than an API through which to call cryptography functions.

I don't like it, but without a change in that license I don't see how
we can include this interface in edk2. One workaround would be to
publish this in a separate repository on https://github.com/OP-TEE/
which could be included in builds using PACKAGES_PATH (like we do with
edk2-platforms and edk2-non-osi).
