From 4963bb2b89884bbdb7e33e6a09c159551e9627aa Mon Sep 17 00:00:00 2001 From: Nick Terrell Date: Thu, 30 Jul 2020 12:08:35 -0700 Subject: lib: Add zstd support to decompress - Add unzstd() and the zstd decompress interface. - Add zstd support to decompress_method(). The decompress_method() and unzstd() functions are used to decompress the initramfs and the initrd. The __decompress() function is used in the preboot environment to decompress a zstd compressed kernel. The zstd decompression function allows the input and output buffers to overlap because that is used by x86 kernel decompression.
