From ce46a9c497ed788146449c230765ee5d6dd3cb53 Mon Sep 17 00:00:00 2001 From: Ben Dooks Date: Tue, 21 Oct 2008 14:06:26 +0100 Subject: [ARM] S3C24XX: Split map.h into plat-s3c24xx and mach-s3c2410 Split the map.h definitions into common S3C24XX code by adding arch/arm/plat-s3c24xx/include/plat/map.h and altering the machine specific header for the S3C24A0. As we add a new we move the original one in arch/arm/plat-s3c include directory to be called map-base.h to distinguish the two files.
