The expression "non-edk2+license" is a typo.

I think you meant "non-BSD-2-Clause-Patent".

I'm OK with commit a4cfb842fca9 being reverted, as this solves the
practical problem of adding generated files.

Acked-by: Laszlo Ersek <ler...@redhat.com>

That said, I *still* don't grasp the more general problem you refer to.

Can we express it as follows (using commits 6b621f958123 and
6f21d772aa6b as reference):

(1) Content under OvmfPkg/Include/IndustryStandard/Xen was introduced
under the MIT license in commit 6b621f958123. That commit was marked with:

> License: This patch adds many files under the MIT licence.
> Contributed-under: TianoCore Contribution Agreement 1.0

and the header files also contained open-coded instances of the MIT
license. (These would later be replaced with SPDX identifiers in commit
6f21d772aa6b.)

As a result, these files effectively granted use and distribution rights
under the MIT license, *plus* a patent grant (per TCA).

(2) If we did the same today (that is, add new MIT-licensed files, but
no "Contributed-under: TCA" line on the commit message), then that would
grant use and distribution rights under the "MIT license", and *no*
patent grant.

Is this the issue you're thinking of?


So are we basically looking to replace (for example):

  SPDX-License-Identifier: MIT

with *something* like:

  SPDX-License-Identifier: MIT-Patent

? (Assuming the latter exists -- which it doesn't, at the moment?)

Thanks
Laszlo
