[PATCH] riscv: boot: add zstd support
From: Jisheng Zhang
Date: Wed Nov 23 2022 - 10:13:01 EST
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.
