+U-Boot for GEC2410
+
+------------------------------------------------
+The supported features of the GEC2410 board are:
+    CPU (Samsung S3C2410 SoC)
+    SDRAM (64 MB , 2 pcs K4S561632, 32 bit)
+    NAND FLASH (64MB , 1 pcs K9F1208)
+    NOR FLASH (only on rev1.1 board, 2MB , 1 pcs SST39VF1601)
+    ETHERNET (10M , 1 pcs CS8900)
+
+
+------------------------------------------------
+Memory Map from CPU point of view:
+
+for NAND FLASH boot:
+    Start	 Size	Access to
+    -----------------------------------------------------
+    0x00000000	 64MB	NAND FLASH (first 4K SRAM for stepptingstone)
+    0x19000300		CS8900 I/O base
+    0x30000000	 64MB	SDRAM
+    0x48000000	 128MB	Special Function Registers Area
+
+
+for NOR FLASH boot:
+    Start	 Size	Access to
+    -----------------------------------------------------
+    0x00000000	 2MB	NOR FLASH
+    0x19000300		CS8900 I/O base

+    0x40000000	 4KB	BootSRAM
+    0x48000000	 128MB	Special Function Registers Area
+
+
+------------------------------------------------
+Setting the board Jumpers & Switches:
+
+   In order to get the board running with the default configuration the
+   jumpers need to be set as follows:
+
+  Core board Jumpers:
+   JP1	close	(Set boot mode, close for booting from NAND FLASH,
+		 otherwise from NOR FLASH)
+
+  Main board Jumpers:
+   J1		close	(Set beep, close for enabling beep, or disabling beep)
+   J18		1-2	(1-2 set RXD2 as UART; 2-3 set RXD2 as IrDA)
+   J9,J10	2-3	(1-2 set USB HOST 1 to Host mode;
+			 2-3 set USB HOST 1 to Device mode)
+   J13		1-2	(1-2 set LCD working power to 5V;
+			 2-3 set LCD working power to 3.3V)
+
+  Core board Switches:
+   S1		open	(Reset button)
+
+  Main board Switches:
+   K1~K16	open	(4x4 keyboard)
+
+
+------------------------------------------------
+LED & Connector Interfaces:
+
+  Core board LEDs:
+   D1,D2	I/O port
+   D3		PWREN pin LED
+   D4		Core board power
+
+  Main board LEDs:
+   D1~D4	GPIO
+   D5,D6	Ethernet
+   D11		Main board power
+
+  Core board Connector Interfaces:
+   J1		JTAG (20 pins)
+
+  Main board Connector Interfaces:
+   RJ1		Ethernet (RJ45)
+   J2		Audio In
+   J3		Audio Out
+   J4		Serial Port 1
+   J5		Serial Port 2
+   U4		IrDA Port
+   J7		USB HOST 0
+   J9		USB HOST 1 / USB DEVICE
+   J11		USB DEVICE
+   J20		GPIO Pins
