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 | |||
