Subject: [PATCH] shutdown: flush console on barebox shutdown
Date: Wed, 30 Sep 2020 15:24:51 +0200 [thread overview]
Message-ID: <20200930132451.354162-1-l.stach@pengutronix.de> (raw)
Same as in the poweroff and restart path, we should make sure to properly
drain the console devices when shutting down barebox. This fixes serial
console corruption when the software running after barebox changes the
peripheral configuration before all the characters have drained out of
the FIFO.
