GenCrc32 tool
Hi Christine!
I think the GenCrc32 usage is different because it just prepends the data

If the guided section was encoded with GenCrc32 tool the resulting
'EFI_GUID_DEFINED_SECTION.DataOffset' field points to the start of
the meaningfull data that follows the CRC32 value.
But if we want to decode the section with GenCrc32 tool we need to
provide a buffer that includes the CRC32 value
