From b130d5c29544fe4cedafd35b112d27a06550d844 Mon Sep 17 00:00:00 2001 From: Kukjin Kim Date: Fri, 3 Feb 2012 14:29:23 +0900 Subject: ARM: S3C24XX: change the ARCH_S3C2410 to ARCH_S3C24XX This patch changes the ARCH name to "ARCH_S3C24XX" for Samsung S3C2410, S3C2412, S3C2413, S3C2416, S3C2440, S3C2442, S3C2443, and S3C2450 SoCs so that we can merge the mach-xxx directories and plat-s3c24xx dir. to just one mach-s3c24xx for them. I think this should be sent to upstream via samsung tree because this touches many samsung stuff.
