Leif:
Shenglei is working on new patch to add license checker as open CI plug-in
(BZ 2833). This way allows to add the exception. So, the autogen file can be
handled. Based on current statement, only BSD-2-Clause-Patent license will be
allowed. Other license can be added as the exception case if necessary. With
new license checker in open CI, I agree to revert this checker in
BaseTools/PatchCheck.py.
Thanks
Liming

Err, yes. Sorry.

Correct.

It doesn't.
For BSD3/BSD4, we can do what the BSD distros do and use (for example)
SPDX-License-Identifier: BSD-3-Clause AND BSD-2-Clause-Patent
It is not clear to me if (for example) "MIT AND BSD-2-Clause-Patent"
is a valid expression. But what about "public domain"? Do we figure out a
jurisdiction in which public domain content can clearly have arbitrary licenses
applied to it and ask someone there to relicense it to something we can accept?
If we decide the explicit patent grant isn't important, why did we add it in
the first place? If we decide it is important, we need to actively make a
decision on whether we can ever sidestep it, and if so under what
circumstances. (e.g.: "we permit it for tools" - but then the code generation
aspect also needs to be covered)
