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
|
|
- S5PC6440
|
|
|
|
S5PC100 and S5PC110 support is currently being merged
|
|
|
|
|
|
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
|
|
s5pc100_defconfig - S5PC100 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-s3c is the s3c24xx/s3c64xx platform directory, although it is currently
|
|
involved in other builds this will be phased out once the relevant code is
|
|
moved elsewhere.
|
|
|
|
plat-s3c24xx is for s3c24xx specific builds, see the S3C24XX docs.
|
|
|
|
plat-s3c64xx is for the s3c64xx specific bits, see the S3C24XX docs.
|
|
|
|
plat-s5p is for s5p specific builds, more to be added.
