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.
