+U-Boot for FriendlyARM Mini2440 (s3c2440)
+
+This file contains information for the port of U-Boot to FriendlyARM
+mini2440
+
+All information about the board can be found on :
+http://www.friendlyarm.net/products/mini2440
+
+To build u-boot : ./MAKEALL mini2440
+
+Overview :
+--------
+FriendlyARM Mini 2440 SBC (Single-Board Computer) with 400 MHz Samsung S3C2440
+ARM9 processor. The board measures 100 x 100 mm, ideal for learning about ARM9
+systems. It's a low cost board.
+
+Boot Methods :
+------------
+Mini2440 can boot from NOR or NAND.
+
+Build :
+-----
+./MAKEALL mini2440
+
+or
+
+make mini2440_config
+make
