Subject: [PATCH 13/14] MACH SAMSUNG/S3C: Re-work the memory detection and handling
Date: Mon,  2 Jan 2012 12:44:01 +0100	[thread overview]
Message-ID: <1325504642-9324-14-git-send-email-jbe@pengutronix.de> (raw)
In-Reply-To: <1325504642-9324-1-git-send-email-jbe@pengutronix.de>

Keep common code in the MACH instead of re-inventing it in each platform.
Also use S3C* macros for all memory related register.
