Re: [PATCH 1/2] test: compression: check with trailing garbage in input

The Linux kernel appends 4 bytes to the end of compressed kernel Images containing the uncompressed image size. They are used to make self-decompressing Images easier. However for archs that don't support self-decompression, like ARM64, U-Boot must be able to decompress the image with the garbage data.

The existing decompressors already support this. This unit test was added while working on zstd support as upstream zstd will error if there is garbage data in the input buffer, and special care was needed to support this.

Applied to u-boot/master, thanks!
