Subject: [U-Boot] [PATCH v3 05/12] OMAP3: Add optimal SDRC autorefresh control values
Date: Wed, 9 Nov 2011 10:10:59 -0700 [thread overview]
Message-ID: <1320858666-17113-6-git-send-email-trini@ti.com> (raw)
In-Reply-To: <1320858666-17113-1-git-send-email-trini@ti.com>
This adds the optimal SDRC autorefresh control register values for
100Mhz, 133MHz, 165MHz and 200MHz clocks. We switch to using this
to provide the default 165MHz value.
