Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

+ 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.
+
+
+Machines
+--------
+
+ The currently supported machines are as follows:
+
+ Simtec Electronics EB2410ITX (BAST)
+
+ A general purpose development board, see EB2410ITX.txt for further
+ details
+
+ Samsung SMDK2410
+
+ Samsung's own development board, geared for PDA work.
+
+ Samsung/Meritech SMDK2440
+
+ The S3C2440 compatible version of the SMDK2440
+
+ Thorcom VR1000
+
+ Custom embedded board
+
+ HP IPAQ 1940
+
+ Handheld (IPAQ), available in several varieties
+
+ HP iPAQ rx3715
+
+ S3C2440 based IPAQ, with a number of variations depending on
+ features shipped.
+
+ Acer N30
+
+ A S3C2410 based PDA from Acer. There is a Wiki page at
+ http://handhelds.org/moin/moin.cgi/AcerN30Documentation .
+
+
+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
