| 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: |
| |
| - S3C64XX: S3C6400 and S3C6410 |
| - S5PC110 / S5PV210 |
| |
| |
| Configuration |
| ------------- |
| |
| A number of configurations are supplied, as there is no current way of |
| unifying all the SoCs into one kernel. |
| |
| 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-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. |
