S3C24XX ARM Linux Overview			==========================Introduction------------  The Samsung S3C24XX range of ARM9 System-on-Chip CPUs are supported  by the 's3c2410' architecture of ARM Linux. Currently the S3C2410 and  the S3C2440 are supported CPUs.Configuration-------------  A generic S3C2410 configuration is provided, and can be used as the  default by `make s3c2410_defconfig`. This configuration has support  for all the machines, and the commonly used features on them.  Certain machines may have their own default configurations as well,  please check the machine specific documentation.Machines--------  The currently supported machines are as follows:  Simtec Electronics EB2410ITX (BAST)    A general purpose development board, see EB2410ITX.txt for further    details  Samsung SMDK2410    Samsung's own development board, geared for PDA work.  Samsung/Meritech SMDK2440    The S3C2440 compatible version of the SMDK2440  Thorcom VR1000    Custom embedded board  HP IPAQ 1940    Handheld (IPAQ), available in several varieties  HP iPAQ rx3715    S3C2440 based IPAQ, with a number of variations depending on    features shipped.  Acer N30    A S3C2410 based PDA from Acer.  There is a Wiki page at    http://handhelds.org/moin/moin.cgi/AcerN30Documentation .Adding New Machines-------------------  The archicture has been designed to support as many machines as can  be configured for it in one kernel build, and any future additions  should keep this in mind before altering items outside of their own  machine files.  Machine definitions should be kept in linux/arch/arm/mach-s3c2410,  and there are a number of examples that can be looked at.  Read the kernel patch submission policies as well as the  Documentation/arm directory before submitting patches. The  ARM kernel series is managed by Russell King, and has a patch system  located at http://www.arm.linux.org.uk/developer/patches/  as well as mailing lists that can be found from the same site.  As a courtesy, please notify <ben-linux@fluff.org> of any new  machines or other modifications.  Any large scale modifications, or new drivers should be discussed  on the ARM kernel mailing list (linux-arm-kernel) before being  attempted.NAND----  The current kernels now have support for the s3c2410 NAND  controller. If there are any problems the latest linux-mtd  CVS can be found from http://www.linux-mtd.infradead.org/Serial------  The s3c2410 serial driver provides support for the internal  serial ports. These devices appear as /dev/ttySAC0 through 3.  To create device nodes for these, use the following commands    mknod ttySAC0 c 204 64    mknod ttySAC1 c 204 65    mknod ttySAC2 c 204 66GPIO----  The core contains support for manipulating the GPIO, see the  documentation in GPIO.txt in the same directory as this file.Clock Management----------------  The core provides the interface defined in the header file  include/asm-arm/hardware/clock.h, to allow control over the  various clock unitsPort Contributors-----------------  Ben Dooks (BJD)  Vincent Sanders  Herbert Potzl  Arnaud Patard (RTP)  Roc Wu  Klaus Fetscher  Dimitry Andric  Shannon Holland  Guillaume Gourat (NexVision)  Christer Weinigel (wingel) (Acer N30)  Lucas Correia Villa Real (S3C2400 port)Document Changes----------------  05 Sep 2004 - BJD - Added Document Changes section  05 Sep 2004 - BJD - Added Klaus Fetscher to list of contributors  25 Oct 2004 - BJD - Added Dimitry Andric to list of contributors  25 Oct 2004 - BJD - Updated the MTD from the 2.6.9 merge  21 Jan 2005 - BJD - Added rx3715, added Shannon to contributors  10 Feb 2005 - BJD - Added Guillaume Gourat to contributors  02 Mar 2005 - BJD - Added SMDK2440 to list of machines  06 Mar 2005 - BJD - Added Christer Weinigel  08 Mar 2005 - BJD - Added LCVR to list of people, updated introduction  08 Mar 2005 - BJD - Added section on adding machinesDocument Author---------------Ben Dooks, (c) 2004-2005 Simtec Electronics
