/** @file
Firmware Volume Block protocol. Consumes FV hobs and creates
appropriate block protocols.
Also consumes NT_NON_MM_FV envinronment variable and produces appropriate
block protocols fro them also... (this is TBD)
Implementations for Firmware Volume Block protocol.
It consumes FV HOBs and creates read-lonly Firmare Volume Block protocol
instances for each of them.
