- 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.
