This document shows an overview of 10*4882a593Smuzhiyun the current kernel support, how to use it and where to find the code 11*4882a593Smuzhiyun that supports this. 12*4882a593Smuzhiyun 13*4882a593Smuzhiyun The currently supported SoCs are: 14*4882a593Smuzhiyun 15*4882a593Smuzhiyun - S3C24XX: See Documentation/arm/samsung-s3c24xx/overview.rst for full list 16*4882a593Smuzhiyun - S3C64XX: S3C6400 and S3C6410 17*4882a593Smuzhiyun - S5PC110 / S5PV210 18*4882a593Smuzhiyun 19*4882a593Smuzhiyun 20*4882a593SmuzhiyunS3C24XX Systems 21*4882a593Smuzhiyun--------------- 22*4882a593Smuzhiyun 23*4882a593Smuzhiyun There is still documentation in Documnetation/arm/Samsung-S3C24XX/ which 24*4882a593Smuzhiyun deals with the architecture and drivers specific to these devices. 25*4882a593Smuzhiyun 26*4882a593Smuzhiyun See Documentation/arm/samsung-s3c24xx/overview.rst for more information 27*4882a593Smuzhiyun on the implementation details and specific support. 28*4882a593Smuzhiyun 29*4882a593Smuzhiyun 30*4882a593SmuzhiyunConfiguration 31*4882a593Smuzhiyun------------- 32*4882a593Smuzhiyun 33*4882a593Smuzhiyun A number of configurations are supplied, as there is no current way of 34*4882a593Smuzhiyun unifying all the SoCs into one kernel. 35*4882a593Smuzhiyun 36*4882a593Smuzhiyun s5pc110_defconfig 37*4882a593Smuzhiyun - S5PC110 specific default configuration 38*4882a593Smuzhiyun s5pv210_defconfig 39*4882a593Smuzhiyun - S5PV210 specific default configuration 40*4882a593Smuzhiyun 41*4882a593Smuzhiyun 42*4882a593SmuzhiyunLayout 43*4882a593Smuzhiyun------ 44*4882a593Smuzhiyun 45*4882a593Smuzhiyun The directory layout is currently being restructured, and consists of 46*4882a593Smuzhiyun several platform directories and then the machine specific directories 47*4882a593Smuzhiyun of the CPUs being built for. 48*4882a593Smuzhiyun 49*4882a593Smuzhiyun plat-samsung provides the base for all the implementations, and is the 50*4882a593Smuzhiyun last in the line of include directories that are processed for the build 51*4882a593Smuzhiyun specific information. It contains the base clock, GPIO and device definitions 52*4882a593Smuzhiyun to get the system running. 53*4882a593Smuzhiyun 54*4882a593Smuzhiyun plat-s3c24xx is for s3c24xx specific builds, see the S3C24XX docs. 55*4882a593Smuzhiyun 56*4882a593Smuzhiyun plat-s5p is for s5p specific builds, and contains common support for the 57*4882a593Smuzhiyun S5P specific systems. Not all S5Ps use all the features in this directory 58*4882a593Smuzhiyun due to differences in the hardware. 59*4882a593Smuzhiyun 60*4882a593Smuzhiyun 61*4882a593SmuzhiyunLayout changes 62*4882a593Smuzhiyun-------------- 63*4882a593Smuzhiyun 64*4882a593Smuzhiyun The old plat-s3c and plat-s5pc1xx directories have been removed, with 65*4882a593Smuzhiyun support moved to either plat-samsung or plat-s5p as necessary. These moves 66*4882a593Smuzhiyun where to simplify the include and dependency issues involved with having 67*4882a593Smuzhiyun so many different platform directories. 68*4882a593Smuzhiyun 69*4882a593Smuzhiyun 70*4882a593SmuzhiyunPort Contributors 71*4882a593Smuzhiyun----------------- 72*4882a593Smuzhiyun 73*4882a593Smuzhiyun Ben Dooks (BJD) 74*4882a593Smuzhiyun Vincent Sanders 75*4882a593Smuzhiyun Herbert Potzl 76*4882a593Smuzhiyun Arnaud Patard (RTP) 77*4882a593Smuzhiyun Roc Wu 78*4882a593Smuzhiyun Klaus Fetscher 79*4882a593Smuzhiyun Dimitry Andric 80*4882a593Smuzhiyun Shannon Holland 81*4882a593Smuzhiyun Guillaume Gourat (NexVision) 82*4882a593Smuzhiyun Christer Weinigel (wingel) (Acer N30) 83*4882a593Smuzhiyun Lucas Correia Villa Real (S3C2400 port) 84*4882a593Smuzhiyun 85*4882a593Smuzhiyun 86*4882a593SmuzhiyunDocument Author 87*4882a593Smuzhiyun--------------- 88*4882a593Smuzhiyun 89*4882a593SmuzhiyunCopyright 2009-2010 Ben Dooks <ben-linux@fluff.org> 90
