Subject: [PATCH 5/7] ARM: zynqmp: zcu104: register update handler
Date: Thu, 24 Jun 2021 12:23:40 +0200	[thread overview]
Message-ID: <20210624102342.269363-6-m.tretter@pengutronix.de> (raw)
In-Reply-To: <20210624102342.269363-1-m.tretter@pengutronix.de>

As the zcu104 stores the environment in the same partition as the
barebox image, the partition is already mounted in ENV_MNT_DIR
("/boot"). Therefore, the update handler has to use the already
existing mount point for the update.
