596   Compressed data (with section header) stays in same location as the source
597   (overwrites source data).
598 
599 Arguments:
600 
601   FileBuffer  - Buffer containing data to Compress
602 
603   BufferSize  - On input, the size of FileBuffer. On output, the size of
604                 actual compressed data (including added section header).
605                 When buffer is too small, this value indicates the size needed.
606 
607   DataSize    - The size of data to compress
608 
609   Type        - The compression type (not used currently).
610                 Assume EFI_HEAVY_COMPRESSION.
611 
612 Returns:
613 
614   EFI_BUFFER_TOO_SMALL - Buffer size is too small.
615   EFI_UNSUPPORTED      - Compress type can not be supported.
616   EFI_SUCCESS          - Successful
617   EFI_OUT_OF_RESOURCES - Not enough resource.
