Subject: [PATCH 2/2] ARM: i.MX: nxp-imx8mm-evk: adjust DDR training order
Date: Wed, 30 Sep 2020 15:24:17 +0200 [thread overview]
Message-ID: <20200930132417.351944-2-l.stach@pengutronix.de> (raw)
In-Reply-To: <20200930132417.351944-1-l.stach@pengutronix.de>
This way we end up with the fastest DDR speed when training is finished
and don't need to rely on TF-A to switch into a higher DDR speed.
Signed-off-by: Lucas Stach <l.stach@pengutronix.de>
