+		Samsung/Meritech SMDK2440
+		=========================
+
+Introduction
+------------
+
+  The SMDK2440 is a two part evaluation board for the Samsung S3C2440
+  processor. It includes support for LCD, SmartMedia, Audio, SD and
+  10MBit Ethernet, and expansion headers for various signals, including
+  the camera and unused GPIO.
+
+
+Configuration
+-------------
+
+  To set the default configuration, use `make smdk2440_defconfig` which
+  will configure the common features of this board, or use
+  `make s3c2410_config` to include support for all s3c2410/s3c2440 machines
+
+
+Support
+-------
+
+  Ben Dooks' SMDK2440 site at http://www.fluff.org/ben/smdk2440/ which
+  includes linux based USB download tools.
+
+  Some of the h1940 patches that can be found from the H1940 project
+  site at http://www.handhelds.org/projects/h1940.html can also be
+  applied to this board.
+
+
+Peripherals
+-----------
+
+  There is no current support for any of the extra peripherals on the
+  base-board itself.
+
+
+MTD
+---
+
+  The NAND flash should be supported by the in kernel MTD NAND support,
+  NOR flash will be added later.
+
+
+Maintainers
+-----------
+
+  This board is being maintained by Ben Dooks, for more info, see
+  http://www.fluff.org/ben/smdk2440/
+
+  Many thanks to Dimitry Andric of TomTom for the loan of the SMDK2440,
+  and to Simtec Electronics for allowing me time to work on this.
+
