Subject: [U-Boot] [PATCHv3 2/3] OMAP3: SDRC: Introduce Numonyx DDR type
Date: Mon, 11 Oct 2010 00:12:34 +0200	[thread overview]
Message-ID: <1286748755-13588-3-git-send-email-eballetbo@gmail.com> (raw)
In-Reply-To: <1286748755-13588-1-git-send-email-eballetbo@gmail.com>

Introduce Numonyx DDR timings and provide CONFIG_OMAP3_NUMONYX_DDR
config options to allow for platform files to setup their timings.
