* libdeflate: Avoid circular dependenciesOlliver Schinagl2023-01-171-5/+12
| | | | | | | | | | | 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.

* tools: Add gzip-libdeflate advanced compressorMarkus Stockhausen2023-01-021-0/+31
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.
