Subject: [PATCH 5/5] api: Rename IMAGE_TYPE to IMAGE_FSTYPES
Date: Mon, 13 Sep 2021 16:58:10 +0200

X-Mailer: git-send-email 2.20.1
In-Reply-To: <20210913145810.26394-1-ubely@ilbers.de>

MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
X-TUID: dYLDQbIWY8J0

The variable is renamed to get closer to OpenEmbedded/Poky
variables naming. If user still uses IMAGE_TYPE, it will be used
with the deprecation warning shown.
