Hello,

Changes for V2
===============
* Replace 2-Clause BSD License in file headers with SPDX-License-Identifier
  statement.  This reduces the size of the file headers and the size
  of the patches for this change.  Based on the following post:

  https://01.org/blogs/jc415/2018/open-source-hacks-one-question-interviews-open-source-experts-how-use-spdx-headers

* Update License.txt in root of edk2 before changing file headers.
* Fix minor typos
===============

This RFC follows up on the proposal from Mark Doran to change the 
EDK II Project to a BSD+Patent License.

	https://lists.01.org/pipermail/edk2-devel/2019-February/036260.html

The review period for this license change is 30 days.  If there is no
unresolved feedback on April 9, 2019, then commits of the license change
patches will begin on April 9, 2019.  

  ** Please provide feedback on the proposal by Monday April 8, 2019. **

Feedback can be sent to edk2-devel@lists.01.org, the EDK II community
manager or any of the EDK II stewards.

The goal is to convert all of the files in the edk2 repository that are
currently covered by the 2-Clause BSD License and the TianoCore
Contribution Agreement to a BSD+Patent License.  

I will be following up with pointers to public GitHub branches that
contain the set of changes to the edk2 repository for review.

The proposal is to perform this change to edk2/master in the steps listed
below. The license change will not be applied to any of the other existing
branches in the edk2 repository.

1) Add a License-History.txt file to the root of the edk2 repository that
   contains the 2-Clause BSD License and the TianoCore Contribution
   Agreement along with the details on the change to the BSD+Patent License.

2) Change License.txt in the root of the edk2 repository from a 2-Clause
   BSD License to the BSD+Patent License. The following is the link to the
   BSD+Patent License and the new License.txt file contents.

   ======================================================================

3) Change all files currently covered by a 2-Clause BSD License and the 
   TianoCore Contribution Agreement to a BSD+Patent License using the 
   following SPDX-License-Identifier statement:

       SPDX-License-Identifier: BSD-2-Clause-Patent

   The use of SPDX-License-Identifier statement is based on the following:

        https://01.org/blogs/jc415/2018/open-source-hacks-one-question-interviews-open-source-experts-how-use-spdx-headers

4) Update Readme.md in the root of the edk2 repository to state that content
   is covered by a BSD+Patent License.  Also state that the BSD+Patent License
   is the preferred license for the EDK II project.

5) Remove the Contributions.txt file from the root of the edk2 repository
   that contains the TianoCore Contribution Agreement.

6) Update all documentation to state that content submitted under the 
   BSD+Patent License no longer requires the Tianocore Contribution
   Agreement which means the following line is not required in commit
   messages for changes to files that are covered by a BSD+Patent License.

       Contributed-under: TianoCore Contribution Agreement 1.1

7) Create Wiki page(s) that provide the details of the BSD+Patent License
   change and provides the status of the license change for each TianoCore
   repository and package.

Once the conversion of the edk2 repository is complete, work will begin
on the other repositories in the TianoCore project.

Best regards,

Mike
