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 | - S5P6440 |
17 | - S5P6442 | |
18 | - S5PC100 | |
19 | - S5PC110 / S5PV210 | |

22 | S3C24XX Systems | |
23 | --------------- | |
24 | ||
25 | There is still documentation in Documnetation/arm/Samsung-S3C24XX/ which | |
26 | deals with the architecture and drivers specific to these devices. | |
27 | ||
28 | See Documentation/arm/Samsung-S3C24XX/Overview.txt for more information | |
29 | on the implementation details and specific support. | |
30 | ||
31 | ||
32 | Configuration | |
33 | ------------- | |
34 | ||
35 | A number of configurations are supplied, as there is no current way of | |
36 | unifying all the SoCs into one kernel. | |
37 | ||
38 | s5p6440_defconfig - S5P6440 specific default configuration | |
1378a7ef | 39 | s5p6442_defconfig - S5P6442 specific default configuration |
a0c814af | 40 | s5pc100_defconfig - S5PC100 specific default configuration |
1378a7ef BD |
41 | s5pc110_defconfig - S5PC110 specific default configuration |
42 | s5pv210_defconfig - S5PV210 specific default configuration | |

45 | Layout | |
46 | ------ | |
47 | ||
48 | The directory layout is currently being restructured, and consists of | |
49 | several platform directories and then the machine specific directories | |
50 | of the CPUs being built for. | |
51 | ||
52 | plat-samsung provides the base for all the implementations, and is the | |
53 | last in the line of include directories that are processed for the build | |
54 | specific information. It contains the base clock, GPIO and device definitions | |
55 | to get the system running. | |
56 | ||
57 | plat-s3c is the s3c24xx/s3c64xx platform directory, although it is currently | |
58 | involved in other builds this will be phased out once the relevant code is | |
59 | moved elsewhere. | |
60 | ||
61 | plat-s3c24xx is for s3c24xx specific builds, see the S3C24XX docs. | |
62 | ||
63 | plat-s3c64xx is for the s3c64xx specific bits, see the S3C24XX docs. | |
64 | ||
65 | plat-s5p is for s5p specific builds, more to be added. | |
66 | ||
