| Samsung ARM Linux Overview |
| ========================== |
| |
| Introduction |
| ------------ |
| |
| The Samsung range of ARM SoCs spans many similar devices, from the initial |
| ARM9 through to the newest ARM cores. This document shows an overview of |
| the current kernel support, how to use it and where to find the code |
| that supports this. |
| |
| The currently supported SoCs are: |
| |
| - S3C24XX: See Documentation/arm/Samsung-S3C24XX/Overview.txt for full list |
| - S3C64XX: S3C6400 and S3C6410 |
| - S5P6440 |
| - S5P6442 |
| - S5PC100 |
| - S5PC110 / S5PV210 |
| |
| |
| S3C24XX Systems |
| --------------- |
| |
| There is still documentation in Documnetation/arm/Samsung-S3C24XX/ which |
| deals with the architecture and drivers specific to these devices. |
| |
| See Documentation/arm/Samsung-S3C24XX/Overview.txt for more information |
| on the implementation details and specific support. |
| |
| |
| Configuration |
| ------------- |
| |
| A number of configurations are supplied, as there is no current way of |
| unifying all the SoCs into one kernel. |
| |
| s5p6440_defconfig - S5P6440 specific default configuration |
| s5p6442_defconfig - S5P6442 specific default configuration |
| s5pc100_defconfig - S5PC100 specific default configuration |
| s5pc110_defconfig - S5PC110 specific default configuration |
| s5pv210_defconfig - S5PV210 specific default configuration |
| |
| |
| Layout |
| ------ |
| |
| The directory layout is currently being restructured, and consists of |
| several platform directories and then the machine specific directories |
| of the CPUs being built for. |
| |
| plat-samsung provides the base for all the implementations, and is the |
| last in the line of include directories that are processed for the build |
| specific information. It contains the base clock, GPIO and device definitions |
| to get the system running. |
| |
| plat-s3c24xx is for s3c24xx specific builds, see the S3C24XX docs. |
| |
| plat-s5p is for s5p specific builds, and contains common support for the |
| S5P specific systems. Not all S5Ps use all the features in this directory |
| due to differences in the hardware. |
| |
| |
| Layout changes |
| -------------- |
| |
| The old plat-s3c and plat-s5pc1xx directories have been removed, with |
| support moved to either plat-samsung or plat-s5p as necessary. These moves |
| where to simplify the include and dependency issues involved with having |
| so many different platform directories. |
| |
| It was decided to remove plat-s5pc1xx as some of the support was already |
| in plat-s5p or plat-samsung, with the S5PC110 support added with S5PV210 |
| the only user was the S5PC100. The S5PC100 specific items where moved to |
| arch/arm/mach-s5pc100. |
