| 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 |

| |
| 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 66 |
| |
| |
| GPIO |
| ---- |
| |
| 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 units |
