Subject: [PATCH v3 2/2] image_types: add Zstandard conversion support
Date: Fri,  8 Nov 2019 09:14:19 +0000	[thread overview]
Message-ID: <20191108091419.25156-2-stefan@agner.ch> (raw)
In-Reply-To: <20191108091419.25156-1-stefan@agner.ch>

From: Stefan Agner <stefan.agner@toradex.com>

Add Zstandard (or just Zstd) compression support. This allows to
create Zstd compressed tarballs by using tar.zst as IMAGE_FSTYPES.
