+ S3C2412 ARM Linux Overview
+ ==========================
+
+Introduction
+------------
+
+ The S3C2412 is part of the S3C24XX range of ARM9 System-on-Chip CPUs
+ from Samsung. This part has an ARM926-EJS core, capable of running up
+ to 266MHz (see data-sheet for more information)
+
+
+Clock
+-----
+
+ The core clock code provides a set of clocks to the drivers, and allows
+ for source selection and a number of other features.
+
+
+Power
+-----
+
+ No support for suspend/resume to RAM in the current system.
+
+
+DMA
+---
+
+ No current support for DMA.
+
+
+GPIO
+----
+
+ There is support for setting the GPIO to input/output/special function
+ and reading or writing to them.
+
+
+UART
+----
+
+ The UART hardware is similar to the S3C2440, and is supported by the
+ s3c2410 driver in the drivers/serial directory.
+
+
+NAND
+----
+
+ The NAND hardware is similar to the S3C2440, and is supported by the
+ s3c2410 driver in the drivers/mtd/nand directory.
+
+
+USB Host
+--------
+
+ The USB hardware is similar to the S3C2410, with extended clock source
+ control. The OHCI portion is supported by the ohci-s3c2410 driver, and
+ the clock control selection is supported by the core clock code.
+
+
+USB Device
+----------
+
+ No current support in the kernel
+
+
+IRQs
+----
+
+ All the standard, and external interrupt sources are supported. The
+ extra sub-sources are not yet supported.
+
+
+RTC
+---
+
+ The RTC hardware is similar to the S3C2410, and is supported by the
+ s3c2410-rtc driver.
+
+
+Watchdog
+--------
+
+ The watchdog harware is the same as the S3C2410, and is supported by
+ the s3c2410_wdt driver.
+
+
+MMC/SD/SDIO
+-----------
+
+ No current support for the MMC/SD/SDIO block.
+
+IIC
+---
+
+ The IIC hardware is the same as the S3C2410, and is supported by the
+ i2c-s3c24xx driver.
+
+
+IIS
+---
+
+ No current support for the IIS interface.
+
+
+SPI
+---
+
+ No current support for the SPI interfaces.
+
+
+ATA
+---
+
+ No current support for the on-board ATA block.
