Subject: [PATCH v9 06/15] memory: tegra20-emc: Print a brief info message about the timings
Date: Tue, 30 Jul 2019 19:56:09 +0300	[thread overview]
Message-ID: <20190730165618.10122-7-digetx@gmail.com> (raw)
In-Reply-To: <20190730165618.10122-1-digetx@gmail.com>

During boot print how many memory timings got the driver and what's the
RAM code. This is a very useful information when something is wrong with
boards memory timing.
