The function to coalesce a fragmented capsule in memory.
@param PeiServices General purpose services available to every PEIM.
@param BlockListBuffer Point to the buffer of Capsule Descriptor Variables.
@param MemoryBase Pointer to the base of a block of memory that we can walk
all over while trying to coalesce our buffers.
On output, this variable will hold the base address of
a coalesced capsule.
@param MemorySize Size of the memory region pointed to by MemoryBase.
On output, this variable will contain the size of the
coalesced capsule.
@retval EFI_NOT_FOUND if we can't determine the boot mode
if the boot mode is not flash-update
if we could not find the capsule descriptors
@retval EFI_BUFFER_TOO_SMALL
if we could not coalesce the capsule in the memory
region provided to us
@retval EFI_SUCCESS if there's no capsule, or if we processed the
capsule successfully.
