/** @file
Boot Logo 2 Protocol is used to convey information of Logo dispayed during boot.

The Boot Logo 2 Protocol is a replacement for the Boot Logo Protocol.  If a
platform produces both the Boot Logo 2 Protocol and the Boot Logo Protocol
then the Boot Logo 2 Protocol must be used instead of the Boot Logo Protocol.
