		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.
