Subject: [PATCH] riscv: boot: add zstd support
Date: Wed, 23 Nov 2022 23:02:57 +0800	[thread overview]
Message-ID: <20221123150257.3108-1-jszhang@kernel.org> (raw)

Support build the zstd compressed Image.zst. Similar as other
compressed formats, the Image.zst is not self-decompressing and
the bootloader still needs to handle decompression before
launching the kernel image.
