[PATCH 5/7] ARM: zynqmp: zcu104: register update handler
From: Michael Tretter <m.tretter@pengutronix.de>
Date: 2021-06-24 10:26:47
Subsystem:
arm port, the rest · Maintainers:
Russell King, Linus Torvalds
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.
