Subject: [U-Boot] [PATCH] Overo GPMC registers
Date: Mon, 25 Jan 2010 10:52:36 -0500 [thread overview]
Message-ID: <1264434756.29002.3.camel@quad> (raw)
Use appropriate GPMC timings for the LAN9221 controller on the
Gumstix Overo expansion boards not the values in arch-omap3/mem.h
which are for a different ethernet controller.
