> The 14 patches in this series add the VariablePolicy feature to the core,
> deprecate Edk2VarLock (while adding a compatibility layer to reduce code
> churn), and integrate the VariablePolicy libraries and protocols into Variable
> Services.
>
> Since the integration requires multiple changes, including adding libraries, a
> protocol, an SMI communication handler, and VariableServices integration,
> the patches are broken up by individual library additions and then a final
> integration. Security-sensitive changes like bypassing Authenticated Variable
> enforcement are also broken out into individual patches so that attention can
> be called directly to them.
>
> Platform porting instructions are described in this wiki entry:
> https://github.com/tianocore/tianocore.github.io/wiki/VariablePolicy-
> Protocol---Enhanced-Method-for-Managing-Variables#platform-porting
>
> Discussion of the feature can be found in multiple places throughout the last
> year on the RFC channel, staging branches, and in devel.
>
> Most recently, this subject was discussed in this thread:
> https://edk2.groups.io/g/devel/message/53712
> (the code branches shared in that discussion are now out of date, but the
> whitepapers and discussion are relevant).
