| 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 | - S5PC110 / S5PV210 |
| 17 | |
| 18 | |
| 19 | S3C24XX Systems |
| 20 | --------------- |
| 21 | |
| 22 | There is still documentation in Documnetation/arm/Samsung-S3C24XX/ which |
| 23 | deals with the architecture and drivers specific to these devices. |
| 24 | |
| 25 | See Documentation/arm/Samsung-S3C24XX/Overview.txt for more information |
| 26 | on the implementation details and specific support. |
| 27 | |
| 28 | |
| 29 | Configuration |
| 30 | ------------- |
| 31 | |
| 32 | A number of configurations are supplied, as there is no current way of |
| 33 | unifying all the SoCs into one kernel. |
| 34 | |
| 35 | s5pc110_defconfig - S5PC110 specific default configuration |
| 36 | s5pv210_defconfig - S5PV210 specific default configuration |
| 37 | |
| 38 | |
| 39 | Layout |
| 40 | ------ |
| 41 | |
| 42 | The directory layout is currently being restructured, and consists of |
| 43 | several platform directories and then the machine specific directories |
| 44 | of the CPUs being built for. |
| 45 | |
| 46 | plat-samsung provides the base for all the implementations, and is the |
| 47 | last in the line of include directories that are processed for the build |
| 48 | specific information. It contains the base clock, GPIO and device definitions |
| 49 | to get the system running. |
| 50 | |
| 51 | plat-s3c24xx is for s3c24xx specific builds, see the S3C24XX docs. |
| 52 | |
| 53 | plat-s5p is for s5p specific builds, and contains common support for the |
| 54 | S5P specific systems. Not all S5Ps use all the features in this directory |
| 55 | due to differences in the hardware. |
| 56 | |
| 57 | |
| 58 | Layout changes |
| 59 | -------------- |
| 60 | |
| 61 | The old plat-s3c and plat-s5pc1xx directories have been removed, with |
| 62 | support moved to either plat-samsung or plat-s5p as necessary. These moves |
| 63 | where to simplify the include and dependency issues involved with having |
| 64 | so many different platform directories. |
