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 | |
| 1378a7ef BD |
16 | - S5PC100 |
| 17 | - S5PC110 / S5PV210 | |

18 | |
| 19 | ||
| 20 | S3C24XX Systems | |
| 21 | --------------- | |
| 22 | ||
| 23 | There is still documentation in Documnetation/arm/Samsung-S3C24XX/ which | |
| 24 | deals with the architecture and drivers specific to these devices. | |
| 25 | ||
| 26 | See Documentation/arm/Samsung-S3C24XX/Overview.txt for more information | |
| 27 | on the implementation details and specific support. | |
| 28 | ||
| 29 | ||
| 30 | Configuration | |
| 31 | ------------- | |
| 32 | ||
| 33 | A number of configurations are supplied, as there is no current way of | |
| 34 | unifying all the SoCs into one kernel. | |
| 35 | ||
| a0c814af | 36 | s5pc100_defconfig - S5PC100 specific default configuration |
| 1378a7ef BD |
37 | s5pc110_defconfig - S5PC110 specific default configuration |
| 38 | s5pv210_defconfig - S5PV210 specific default configuration | |

| 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 | ||
| a0c814af BD |
53 | plat-s3c24xx is for s3c24xx specific builds, see the S3C24XX docs. |
| 54 | ||
| 1b03ef46 BD |
55 | plat-s5p is for s5p specific builds, and contains common support for the |
| 56 | S5P specific systems. Not all S5Ps use all the features in this directory | |
| 57 | due to differences in the hardware. | |
| 58 | ||
| 59 | ||
| 60 | Layout changes | |
| 61 | -------------- | |
| 62 | ||
| 63 | The old plat-s3c and plat-s5pc1xx directories have been removed, with | |
| 64 | support moved to either plat-samsung or plat-s5p as necessary. These moves | |
| 65 | where to simplify the include and dependency issues involved with having | |
| 66 | so many different platform directories. | |
| a0c814af | 67 | |
| 1b03ef46 BD |
68 | It was decided to remove plat-s5pc1xx as some of the support was already |
| 69 | in plat-s5p or plat-samsung, with the S5PC110 support added with S5PV210 | |
| 70 | the only user was the S5PC100. The S5PC100 specific items where moved to | |
| 71 | arch/arm/mach-s5pc100. | |
