| 1 | niro | 628 | S3C24XX ARM Linux Overview |
| 2 | ========================== | ||
| 3 | |||
| 4 | |||
| 5 | |||
| 6 | Introduction | ||
| 7 | ------------ | ||
| 8 | |||
| 9 | The Samsung S3C24XX range of ARM9 System-on-Chip CPUs are supported | ||
| 10 | by the 's3c2410' architecture of ARM Linux. Currently the S3C2410 and | ||
| 11 | the S3C2440 are supported CPUs. | ||
| 12 | |||
| 13 | |||
| 14 | Configuration | ||
| 15 | ------------- | ||
| 16 | |||
| 17 | A generic S3C2410 configuration is provided, and can be used as the | ||
| 18 | default by `make s3c2410_defconfig`. This configuration has support | ||
| 19 | for all the machines, and the commonly used features on them. | ||
| 20 | |||
| 21 | Certain machines may have their own default configurations as well, | ||
| 22 | please check the machine specific documentation. | ||
| 23 | |||
| 24 | |||
| 25 | Machines | ||
| 26 | -------- | ||
| 27 | |||
| 28 | The currently supported machines are as follows: | ||
| 29 | |||
| 30 | Simtec Electronics EB2410ITX (BAST) | ||
| 31 | |||
| 32 | A general purpose development board, see EB2410ITX.txt for further | ||
| 33 | details | ||
| 34 | |||
| 35 | Samsung SMDK2410 | ||
| 36 | |||
| 37 | Samsung's own development board, geared for PDA work. | ||
| 38 | |||
| 39 | Samsung/Meritech SMDK2440 | ||
| 40 | |||
| 41 | The S3C2440 compatible version of the SMDK2440 | ||
| 42 | |||
| 43 | Thorcom VR1000 | ||
| 44 | |||
| 45 | Custom embedded board | ||
| 46 | |||
| 47 | HP IPAQ 1940 | ||
| 48 | |||
| 49 | Handheld (IPAQ), available in several varieties | ||
| 50 | |||
| 51 | HP iPAQ rx3715 | ||
| 52 | |||
| 53 | S3C2440 based IPAQ, with a number of variations depending on | ||
| 54 | features shipped. | ||
| 55 | |||
| 56 | Acer N30 | ||
| 57 | |||
| 58 | A S3C2410 based PDA from Acer. There is a Wiki page at | ||
| 59 | http://handhelds.org/moin/moin.cgi/AcerN30Documentation . | ||
| 60 | |||
| 61 | |||
| 62 | Adding New Machines | ||
| 63 | ------------------- | ||
| 64 | |||
| 65 | The archicture has been designed to support as many machines as can | ||
| 66 | be configured for it in one kernel build, and any future additions | ||
| 67 | should keep this in mind before altering items outside of their own | ||
| 68 | machine files. | ||
| 69 | |||
| 70 | Machine definitions should be kept in linux/arch/arm/mach-s3c2410, | ||
| 71 | and there are a number of examples that can be looked at. | ||
| 72 | |||
| 73 | Read the kernel patch submission policies as well as the | ||
| 74 | Documentation/arm directory before submitting patches. The | ||
| 75 | ARM kernel series is managed by Russell King, and has a patch system | ||
| 76 | located at http://www.arm.linux.org.uk/developer/patches/ | ||
| 77 | as well as mailing lists that can be found from the same site. | ||
| 78 | |||
| 79 | As a courtesy, please notify <ben-linux@fluff.org> of any new | ||
| 80 | machines or other modifications. | ||
| 81 | |||
| 82 | Any large scale modifications, or new drivers should be discussed | ||
| 83 | on the ARM kernel mailing list (linux-arm-kernel) before being | ||
| 84 | attempted. | ||
| 85 | |||
| 86 | |||
| 87 | NAND | ||
| 88 | ---- | ||
| 89 | |||
| 90 | The current kernels now have support for the s3c2410 NAND | ||
| 91 | controller. If there are any problems the latest linux-mtd | ||
| 92 | CVS can be found from http://www.linux-mtd.infradead.org/ | ||
| 93 | |||
| 94 | |||
| 95 | Serial | ||
| 96 | ------ | ||
| 97 | |||
| 98 | The s3c2410 serial driver provides support for the internal | ||
| 99 | serial ports. These devices appear as /dev/ttySAC0 through 3. | ||
| 100 | |||
| 101 | To create device nodes for these, use the following commands | ||
| 102 | |||
| 103 | mknod ttySAC0 c 204 64 | ||
| 104 | mknod ttySAC1 c 204 65 | ||
| 105 | mknod ttySAC2 c 204 66 | ||
| 106 | |||
| 107 | |||
| 108 | GPIO | ||
| 109 | ---- | ||
| 110 | |||
| 111 | The core contains support for manipulating the GPIO, see the | ||
| 112 | documentation in GPIO.txt in the same directory as this file. | ||
| 113 | |||
| 114 | |||
| 115 | Clock Management | ||
| 116 | ---------------- | ||
| 117 | |||
| 118 | The core provides the interface defined in the header file | ||
| 119 | include/asm-arm/hardware/clock.h, to allow control over the | ||
| 120 | various clock units | ||
| 121 | |||
