0002 Samsung ARM Linux Overview
0003 ==========================
0004
0005 Introduction
0006 ------------
0007
0008 The Samsung range of ARM SoCs spans many similar devices, from the initial
0009 ARM9 through to the newest ARM cores. This document shows an overview of
0010 the current kernel support, how to use it and where to find the code
0011 that supports this.
0012
0013 The currently supported SoCs are:
0014
0015 - S3C24XX: See Documentation/arm/samsung-s3c24xx/overview.rst for full list
0016 - S3C64XX: S3C6400 and S3C6410
0017 - S5PC110 / S5PV210
0018
0019
0020 S3C24XX Systems
0021 ---------------
0022
0023 There is still documentation in Documnetation/arm/Samsung-S3C24XX/ which
0024 deals with the architecture and drivers specific to these devices.
0025
0026 See Documentation/arm/samsung-s3c24xx/overview.rst for more information
0027 on the implementation details and specific support.
0028
0029
0030 Configuration
0031 -------------
0032
0033 A number of configurations are supplied, as there is no current way of
0034 unifying all the SoCs into one kernel.
0035
0036 s5pc110_defconfig
0037 - S5PC110 specific default configuration
0038 s5pv210_defconfig
0039 - S5PV210 specific default configuration
0040
0041
0042 Layout
0043 ------
0044
0045 The directory layout is currently being restructured, and consists of
0046 several platform directories and then the machine specific directories
0047 of the CPUs being built for.
0048
0049 plat-samsung provides the base for all the implementations, and is the
0050 last in the line of include directories that are processed for the build
0051 specific information. It contains the base clock, GPIO and device definitions
0052 to get the system running.
0053
0054 plat-s3c24xx is for s3c24xx specific builds, see the S3C24XX docs.
0055
0056 plat-s5p is for s5p specific builds, and contains common support for the
0057 S5P specific systems. Not all S5Ps use all the features in this directory
0058 due to differences in the hardware.
0059
0060
0061 Layout changes
0062 --------------
0063
0064 The old plat-s3c and plat-s5pc1xx directories have been removed, with
0065 support moved to either plat-samsung or plat-s5p as necessary. These moves
0066 where to simplify the include and dependency issues involved with having
0067 so many different platform directories.
