This driver searches APPLICATION in FV and installs LoadFile protocol for every found one. Then, BDS will add BootOption for LoadFile protocol.
It provides the generic way to expose boot option for the internal application, such as Shell. With this driver, PlatformBds doesn’t need to specially handle Shell application.
