Subject: [PATCH] uboot-envtools: mvebu: update uci defaults for Turris Omnia
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

From version 2021.09 U-Boot will fixup Turris Omnia's DTB before
booting, separating U-Boot's environment into separate MTD partition
"u-boot-env" [1].

Check if "u-boot-env" MTD partition exists and set the uci defaults
accordingly.
