[RFC] Change EDK II to an Apache 2.0 License

["Kinney, Michael D" <michael.d.kinney@intel.com>]

Hello,

This RFC follows up on the proposal from Mark Doran to change the 
EDK II Project to an Apache 2.0 License.

    https://lists.01.org/pipermail/edk2-devel/2018-October/030385.html


  ** Please provide feedback on the proposal by Friday 12/7/18. **

I will be following up with pointers to public GitHub branches that
contain the initial set of changes in steps (1) and (2) below 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) Change all files with a BSD 2-Clause license and only a single 
   copyright statement by Intel Corporation to an Apache 2.0 license
   and add an SPDX-License-Identifier statement.

2) Update Readme.md and License.txt in the root of the edk2 repository to
   state that content is covered by a mix of BSD 2-Clause and Apache 2.0
   licenses. 

3) Update all documentation to state that content submitted under the 
   Apache 2.0 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 an Apache 2.0 License.

       Contributed-under: TianoCore Contribution Agreement 1.1

4) Create Wiki page(s) that provide the details of the Apache 2.0 License
   change and provide the status of the license change for each package
   in the edk2 repository.  Also provide a list of the additional copyright
   holders that need to be contacted to accept the change to an Apache 2.0
   License along with the status of that acceptance.

5) After all copyright holders have accepted the change to an Apache 2.0
   License, change the remaining files from BSD 2-Clause to Apache 2.0.

6) Update Readme.md and License.txt in the edk2 repository to state that
   Apache 2.0 is the preferred license for the EDK II project.

Best regards,

Mike
