Subject: [PATCH v1] ARM: dts: imx6q-prti6q: add pstore/ramoops node
Date: Thu, 8 Oct 2020 13:07:34 +0200 [thread overview]
Message-ID: <20201008110734.31719-1-o.rempel@pengutronix.de> (raw)
In some cases we have no UART access, but we still need to get barebox
messages. With ramoops enabled, we still can get barebox message from
running Linux by reading:
cat /sys/fs/pstore/console-ramoops-0
