		Samsung ARM Linux Overview

2
		==========================

Introduction

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

S3C24XX 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.

31
Configuration

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

43
Layout

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


62
Layout 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.
