   1                Samsung ARM Linux Overview
   2                ==========================

   4Introduction
   5------------
   6
   7  The Samsung range of ARM SoCs spans many similar devices, from the initial
   8  ARM9 through to the newest ARM cores. This document shows an overview of
   9  the current kernel support, how to use it and where to find the code
  10  that supports this.
  11
  12  The currently supported SoCs are:
  13
  14  - S3C24XX: See Documentation/arm/Samsung-S3C24XX/Overview.txt for full list
  15  - S3C64XX: S3C6400 and S3C6410
  16  - S5P6440
  17  - S5PC100
  18  - S5PC110 / S5PV210

  21S3C24XX Systems
  22---------------
  23
  24  There is still documentation in Documnetation/arm/Samsung-S3C24XX/ which
  25  deals with the architecture and drivers specific to these devices.
  26
  27  See Documentation/arm/Samsung-S3C24XX/Overview.txt for more information
  28  on the implementation details and specific support.
  29
  30
  31Configuration
  32-------------
  33
  34  A number of configurations are supplied, as there is no current way of
  35  unifying all the SoCs into one kernel.
  36
  37  s5p6440_defconfig - S5P6440 specific default configuration
  38  s5pc100_defconfig - S5PC100 specific default configuration
  39  s5pc110_defconfig - S5PC110 specific default configuration
  40  s5pv210_defconfig - S5PV210 specific default configuration
  41

  43Layout
  44------
  45
  46  The directory layout is currently being restructured, and consists of
  47  several platform directories and then the machine specific directories
  48  of the CPUs being built for.
  49
  50  plat-samsung provides the base for all the implementations, and is the
  51  last in the line of include directories that are processed for the build
  52  specific information. It contains the base clock, GPIO and device definitions
  53  to get the system running.
  54
  55  plat-s3c24xx is for s3c24xx specific builds, see the S3C24XX docs.
  56
  57  plat-s5p is for s5p specific builds, and contains common support for the
  58  S5P specific systems. Not all S5Ps use all the features in this directory
  59  due to differences in the hardware.
  60
  61
  62Layout changes
  63--------------
  64
  65  The old plat-s3c and plat-s5pc1xx directories have been removed, with
  66  support moved to either plat-samsung or plat-s5p as necessary. These moves
  67  where to simplify the include and dependency issues involved with having
  68  so many different platform directories.
  69
  70  It was decided to remove plat-s5pc1xx as some of the support was already
  71  in plat-s5p or plat-samsung, with the S5PC110 support added with S5PV210
  72  the only user was the S5PC100. The S5PC100 specific items where moved to
  73  arch/arm/mach-s5pc100.
