Subject: [PATCH] ARM: rdu-common: restart machine after fixing i210 device ID
Date: Tue, 17 Dec 2019 12:22:38 +0100 [thread overview]
Message-ID: <20191217112238.32333-1-l.stach@pengutronix.de> (raw)
For the iNVM change to take effect we need to reset the i210 adapter.
As this is not really possible in isolation in Barebox, we just go
through a full machine reset cycle. As this should only happen once
during the lifetime of each device there is no need for a more
elaborate solution.
