Olliver Schinagl	62e150949f	libdeflate: Avoid circular dependencies ... CMake depends on (libdeflate-)gunzip, libdeflate depends on Cmake, so we can't win. Luckily libdeflate is _very_ easy to build, without any build system, so lets just manually compile it and be done with it.

Olliver Schinagl	9a59bf3528	libdeflate: Update to v1.17 ... The new version of libdeflate makes it a little easier to build it without any build system. Signed-off-by: Olliver Schinagl <oliver@schinagl.nl>	2023-01-17 20:55:18 +01:00
Markus Stockhausen	a51ca085bf	tools: Add gzip-libdeflate advanced compressor ... Several devices provide U-Boot versions with only gzip compressed kernel support (e.g. Realtek switches). This compression method produces larger images than lzma. To save space on flash and avoid going the hard way with lzma-loader we can make use of enhanced gzip tool based on libdeflate compression library from https://github.com/ebiggers/libdeflate. It keeps 100% deflate/gzip compatibility while improving compression ratio. The image can be unpacked by the default inflate routines inside U-Boot.
