- Add commit to avoid duplicates in bintool lists
- Add commit to forward AddBintools calls
- Add commit to forward AddBintools calls to base class
- Add commit to collect bintools before usage
- Add commit to check only section data in multi section test
- Add commit to add DecompressData function to entry class
- Fix decompress
- Disable header in testInvalidCompress function
- Remove header value in testInvalidCompress
- Add commit to move compression bintools creation into test setup
- Add commit to select compression bintools in cbfs_util class
- Add commit to move compression bintool management into entry class
- Use record_missing_bintool function
- Use tools.get_bytes function
- Add support to DecompressData function
- Reuse 85_compress_section.dts file
- Remove 236_compress_dtb_missing_bintool.dts file
- Use self.comp_bintools dict
- Use _CheckBintool(bintool) function
- Remove self.fetch_package not None check in fetch function
- Add algorithm name to entry.py
- Add tool name to ftest.py
- Add algorithm name to entry.py
- Add tool name to ftest.py
- Add algorithm name to entry.py
- Add tool name to entry.py and ftest.py
- Add algorithm name to entry.py
- Add tool name to ftest.py
- Test that zstd compress of device-tree files failed
- Add algorithm name to entry.py
- Add tool name to ftest.py

Changes in v4:
- Add missing 236_compress_dtb_missing_bintool.dts file

Changes in v3:
- Move comp_util.py changes (drop with_header) into separate commits.
- Add commit to disable compressed data header
- Add commit to remove obsolete compressed data header handling
- Add commit to support missing compression tools
- Use 'tools.get_bytes(0, 64)' instead of 'bytes([0]) * 64'
- Check if tool is present
- Rename tests
- Document class properties

Changes in v2:
- Add commit to skip elf tests
- Reworked to make the feature optional.
- Add commit to add compression tests
- Add commit to add BintoolPacker class to bintool
- Add commit to add bzip2 bintool
- Add commit to add gzip bintool
- Add commit to add lzop bintool
- Add commit to add xz bintool
- Add commit to add zstd bintool
