1 | Samsung ARM Linux Overview |
| 2 | ========================== | |
| 3 | ||
| 4 | Introduction | |
| 5 | ------------ | |
| 6 | ||
| 7 | The Samsung range of ARM SoCs spans many similar devices, from the initial | |
| 8 | ARM9 through to the newest ARM cores. This document shows an overview of | |
| 9 | the current kernel support, how to use it and where to find the code | |
| 10 | that supports this. | |
| 11 | ||
| 12 | The currently supported SoCs are: | |
| 13 | ||
| 14 | - S3C24XX: See Documentation/arm/Samsung-S3C24XX/Overview.txt for full list | |
| 15 | - S3C64XX: S3C6400 and S3C6410 | |
| 16 | - S5PC6440 | |
| 17 | ||
| 18 | S5PC100 and S5PC110 support is currently being merged | |
| 19 | ||
| 20 | ||
| 21 | S3C24XX Systems | |
| 22 | --------------- | |
| 23 | ||
| 24 | There is still documentation in Documnetation/arm/Samsung-S3C24XX/ which | |
| 25 | deals with the architecture and drivers specific to these devices. | |
| 26 | ||
| 27 | See Documentation/arm/Samsung-S3C24XX/Overview.txt for more information | |
| 28 | on the implementation details and specific support. | |
| 29 | ||
| 30 | ||
| 31 | Configuration | |
| 32 | ------------- | |
| 33 | ||
| 34 | A number of configurations are supplied, as there is no current way of | |
| 35 | unifying all the SoCs into one kernel. | |
| 36 | ||
| 37 | s5p6440_defconfig - S5P6440 specific default configuration | |
| 38 | s5pc100_defconfig - S5PC100 specific default configuration | |
| 39 | ||
| 40 | ||
| 41 | Layout | |
| 42 | ------ | |
| 43 | ||
| 44 | The directory layout is currently being restructured, and consists of | |
| 45 | several platform directories and then the machine specific directories | |
| 46 | of the CPUs being built for. | |
| 47 | ||
| 48 | plat-samsung provides the base for all the implementations, and is the | |
| 49 | last in the line of include directories that are processed for the build | |
| 50 | specific information. It contains the base clock, GPIO and device definitions | |
| 51 | to get the system running. | |
| 52 | ||
| 53 | plat-s3c is the s3c24xx/s3c64xx platform directory, although it is currently | |
| 54 | involved in other builds this will be phased out once the relevant code is | |
| 55 | moved elsewhere. | |
| 56 | ||
| 57 | plat-s3c24xx is for s3c24xx specific builds, see the S3C24XX docs. | |
| 58 | ||
| 59 | plat-s3c64xx is for the s3c64xx specific bits, see the S3C24XX docs. | |
| 60 | ||
| 61 | plat-s5p is for s5p specific builds, more to be added. | |
| 62 | ||
| 63 | ||
| 64 | [ to finish ] | |
