Subject: [U-Boot] [PATCH 1/2] U-Boot/SPL: omap4: Make ddr pre-calculated timings as default.
Date: Tue, 27 Sep 2011 17:13:18 +0530	[thread overview]
Message-ID: <1317123799-5480-2-git-send-email-r.sricharan@ti.com> (raw)
In-Reply-To: <1317123799-5480-1-git-send-email-r.sricharan@ti.com>

All ddr configurations(geometry/timings) are done automatically
by detecting the device connected at run time. Though this
is a useful feature, making this as a default setting increases
the code size by about 2K bytes. This is quite big, especially
in the case of SPL which runs from a smaller SRAM. So do not
use this feature as the default setting, instead use the
precalculated tables.
