https://github.com/Microsoft/MS_UEFI/commit/33bab4031a417d7d5a7d356c15a14c2e60302b2d

Add new Boot Logo 2 Protocol that adds a GetBootLogo()
service that can be used to retrieve the GOP BLT buffer,
location, and size of the boot logo that was previously
registered with the SetBootLogo() service.

The Boot Logo 2 Protocol service GetBootLogo() is amended
to return the pointer to the GOP BLT buffer previously
registered with the SetBootLogo() service.
