Firmware Volume Block Protocol Runtime Abstraction
mFvbEntry is an array of Handle Fvb pairs. The Fvb Lib Instance matches the
index in the mFvbEntry array. This should be the same sequence as the FVB's
were described in the HOB. We have to remember the handle so we can tell if
the protocol has been reinstalled and it needs updateing.
If you are using any of these lib functions.you must first call FvbInitialize ().
