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 20 21 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 43 44 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. 76 77 78 79 80Port Contributors 81----------------- 82 83 Ben Dooks (BJD) 84 Vincent Sanders 85 Herbert Potzl 86 Arnaud Patard (RTP) 87 Roc Wu 88 Klaus Fetscher 89 Dimitry Andric 90 Shannon Holland 91 Guillaume Gourat (NexVision) 92 Christer Weinigel (wingel) (Acer N30) 93 Lucas Correia Villa Real (S3C2400 port) 94 95 96Document Author 97--------------- 98 99Copyright 2009-2010 Ben Dooks <ben-linux@fluff.org> 100
