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

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.

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
Ben Dooks1378a7e2010-05-24 10:33:50 +0900[diff] [blame]39 s5pc110_defconfig - S5PC110 specific default configuration
40 s5pv210_defconfig - S5PV210 specific default configuration

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
Ben Dooksa0c814a2009-11-23 23:32:31 +0000[diff] [blame]55 plat-s3c24xx is for s3c24xx specific builds, see the S3C24XX docs.
56
Ben Dooks1b03ef42010-05-24 10:48:02 +0900[diff] [blame]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.

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.
