+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
+ 0x30000000 64MB SDRAM
+ 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
