+		Samsung ARM Linux Overview
+		==========================
+
+Introduction
+------------
+
+  The Samsung range of ARM SoCs spans many similar devices, from the initial
+  ARM9 through to the newest ARM cores. This document shows an overview of
+  the current kernel support, how to use it and where to find the code
+  that supports this.
+
+  The currently supported SoCs are:
+
+  - S3C24XX: See Documentation/arm/Samsung-S3C24XX/Overview.txt for full list
+  - S3C64XX: S3C6400 and S3C6410
+  - S5PC6440
+
+  S5PC100 and S5PC110 support is currently being merged
+
+
+S3C24XX Systems
+---------------
+
+  There is still documentation in Documnetation/arm/Samsung-S3C24XX/ which
+  deals with the architecture and drivers specific to these devices.
+
+  See Documentation/arm/Samsung-S3C24XX/Overview.txt for more information
+  on the implementation details and specific support.
+
+
+Configuration
+-------------
+
+  A number of configurations are supplied, as there is no current way of
+  unifying all the SoCs into one kernel.
+
+  s5p6440_defconfig - S5P6440 specific default configuration
+  s5pc100_defconfig - S5PC100 specific default configuration
+
+
+Layout
+------
+
+  The directory layout is currently being restructured, and consists of
+  several platform directories and then the machine specific directories
+  of the CPUs being built for.
+
+  plat-samsung provides the base for all the implementations, and is the
+  last in the line of include directories that are processed for the build
+  specific information. It contains the base clock, GPIO and device definitions
+  to get the system running.
+
+  plat-s3c is the s3c24xx/s3c64xx platform directory, although it is currently
+  involved in other builds this will be phased out once the relevant code is
+  moved elsewhere.
+
+  plat-s3c24xx is for s3c24xx specific builds, see the S3C24XX docs.
+
+  plat-s3c64xx is for the s3c64xx specific bits, see the S3C24XX docs.
+
+  plat-s5p is for s5p specific builds, more to be added.
+
+
+  [ to finish ]
