From 9f6a503d5238f444b13aaeaf8b88032dbcc5b707 Mon Sep 17 00:00:00 2001 From: Jisheng Zhang Date: Mon, 20 Jun 2022 01:06:57 +0800 Subject: [PATCH] arm64: boot: add zstd support 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.
