Firmware Volume Block Protocol Runtime Interface Abstraction
And FVB Extension protocol Runtime Interface 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 ().

EfiFvbReadBlock() function must return the status code EFI_ACCESS_DENIED
without modifying the contents of the buffer.
The EfiFvbReadBlock() function must also prevent spanning block boundaries.
If a read is requested that would span a block boundary, the read must read

Writes specified number of bytes from the input buffer to the block
The EfiFvbWriteBlock() function writes the specified number of bytes
from the provided buffer to the specified block and offset in the
requested firmware volume.
If the firmware volume is sticky write, the caller must ensure that
all the bits of the specified range to write are in the EFI_FVB_ERASE_POLARITY
state before calling the EfiFvbWriteBlock() function, or else the
result will be unpredictable. This unpredictability arises because,
for a sticky-write firmware volume, a write may negate a bit in the
EFI_FVB_ERASE_POLARITY state but it cannot flip it back again. In
general, before calling the EfiFvbWriteBlock() function, the caller
should call the EfiFvbEraseBlock() function first to erase the specified
block to write. A block erase cycle will transition bits from the
(NOT)EFI_FVB_ERASE_POLARITY state back to the EFI_FVB_ERASE_POLARITY state.
Implementations should be mindful that the firmware volume might be
in the WriteDisabled state. If it is in this state, the EfiFvbWriteBlock()
function must return the status code EFI_ACCESS_DENIED without modifying
the contents of the firmware volume.
The EfiFvbWriteBlock() function must also prevent spanning block boundaries.
If a write is requested that spans a block boundary, the write must store
up to the boundary but not beyond. The output parameter NumBytes must be
set to correctly indicate the number of bytes actually written. The caller
must be aware that a write may be partially completed.
