1 Samsung ARM Linux Overview
2 ==========================
3
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 - S5P6442
18 - S5PC100
19 - S5PC110 / S5PV210

22S3C24XX Systems
23---------------
24
25 There is still documentation in Documnetation/arm/Samsung-S3C24XX/ which
26 deals with the architecture and drivers specific to these devices.
27
28 See Documentation/arm/Samsung-S3C24XX/Overview.txt for more information
29 on the implementation details and specific support.
30
31
32Configuration
33-------------
34
35 A number of configurations are supplied, as there is no current way of
36 unifying all the SoCs into one kernel.
37
38 s5p6440_defconfig - S5P6440 specific default configuration
39 s5p6442_defconfig - S5P6442 specific default configuration
40 s5pc100_defconfig - S5PC100 specific default configuration
41 s5pc110_defconfig - S5PC110 specific default configuration
42 s5pv210_defconfig - S5PV210 specific default configuration

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