S3C24XX ARM Linux Overview
|
||
|
|
==========================
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
Introduction
|
||
|
|
------------
|
||
|
|
|
||
|
|
The Samsung S3C24XX range of ARM9 System-on-Chip CPUs are supported
|
||
|
|
by the 's3c2410' architecture of ARM Linux. Currently the S3C2410 and
|
||
|
|
the S3C2440 are supported CPUs.
|
||
|
|
|
||
|
|
|
||
|
|
Configuration
|
||
|
|
-------------
|
||
|
|
|
||
|
|
A generic S3C2410 configuration is provided, and can be used as the
|
||
|
|
default by `make s3c2410_defconfig`. This configuration has support
|
||
|
|
for all the machines, and the commonly used features on them.
|
||
|
|
|
||
|
|
Certain machines may have their own default configurations as well,
|
||
|
|
please check the machine specific documentation.
|
||

Adding New Machines
|
||
|
|
-------------------
|
||
|
|
|
||
|
|
The archicture has been designed to support as many machines as can
|
||
|
|
be configured for it in one kernel build, and any future additions
|
||
|
|
should keep this in mind before altering items outside of their own
|
||
|
|
machine files.
|
||
|
|
|
||
|
|
Machine definitions should be kept in linux/arch/arm/mach-s3c2410,
|
||
|
|
and there are a number of examples that can be looked at.
|
||
|
|
|
||
|
|
Read the kernel patch submission policies as well as the
|
||
|
|
Documentation/arm directory before submitting patches. The
|
||
|
|
ARM kernel series is managed by Russell King, and has a patch system
|
||
|
|
located at http://www.arm.linux.org.uk/developer/patches/
|
||
|
|
as well as mailing lists that can be found from the same site.
|
||
|
|
|
||
|
|
As a courtesy, please notify <ben-linux@fluff.org> of any new
|
||
|
|
machines or other modifications.
|
||
|
|
|
||
|
|
Any large scale modifications, or new drivers should be discussed
|
||
|
|
on the ARM kernel mailing list (linux-arm-kernel) before being
|
||
|
|
attempted.
|
||
|
|
|
||
|
|
|
||
|
|
NAND
|
||
|
|
----
|
||
|
|
|
||
|
|
The current kernels now have support for the s3c2410 NAND
|
||
|
|
controller. If there are any problems the latest linux-mtd
|
||
|
|
CVS can be found from http://www.linux-mtd.infradead.org/
|
||
|
|
|
||
|
|
|
||
|
|
Serial
|
||
|
|
------
|
||
|
|
|
||
|
|
The s3c2410 serial driver provides support for the internal
|
||
|
|
serial ports. These devices appear as /dev/ttySAC0 through 3.
|
||
|
|
|
||
|
|
To create device nodes for these, use the following commands
|
||
|
|
|
||
|
|
mknod ttySAC0 c 204 64
|
||
|
|
mknod ttySAC1 c 204 65
|
||
|
|
mknod ttySAC2 c 204 66
|
||
|
|
|
||
|
|
|
||
|
|
GPIO
|
||
|
|
----
|
||
|
|
|
||
|
|
The core contains support for manipulating the GPIO, see the
|
||
|
|
documentation in GPIO.txt in the same directory as this file.
|
||
|
|
|
||
|
|
|
||
|
|
Clock Management
|
||
|
|
----------------
|
||
|
|
|
||
|
|
The core provides the interface defined in the header file
|
||
|
|
include/asm-arm/hardware/clock.h, to allow control over the
|
||
|
|
various clock units
