Subject: [U-Boot] [PATCH v1 4/4] ARM: vf610: ddrmc: do not write CR79 by default
Date: Tue,  4 Dec 2018 11:10:21 +0100	[thread overview]
Message-ID: <20181204101021.22817-5-stefan@agner.ch> (raw)
In-Reply-To: <20181204101021.22817-1-stefan@agner.ch>

From: Stefan Agner <stefan.agner@toradex.com>

The current value CTLUPD_AREF(0) is the reset value of the register,
so there is no need to write a value. If needed, the register can be
written using board specific CR settings.
