Routine Description:

  The implementation is same as that  of EFI_DECOMPRESS_PROTOCOL.GetInfo().

Arguments:

  This        - The protocol instance pointer
  Source      - The source buffer containing the compressed data.
  SrcSize     - The size of source buffer
  DstSize     - The size of destination buffer.
  ScratchSize - The size of scratch buffer.

Returns:

  EFI_SUCCESS           - The size of destination buffer and the size of scratch buffer are successull retrieved.
  EFI_INVALID_PARAMETER - The source data is corrupted

Routine Description:

Arguments:

  This        - The protocol instance pointer
  Source      - The source buffer containing the compressed data.
  SrcSize     - The size of source buffer
  Destination - The destination buffer to store the decompressed data
  DstSize     - The size of destination buffer.
  Scratch     - The buffer used internally by the decompress routine. This  buffer is needed to store intermediate data.
  ScratchSize - The size of scratch buffer.

Returns:

  EFI_SUCCESS           - Decompression is successfull
  EFI_INVALID_PARAMETER - The source data is corrupted
