+Renesas Technology R0P7785LC0011RL board
+========================================
+
+This board specification:
+=========================
+
+The R0P7785LC0011RL(board config name:sh7785lcr) has the following device:
+
+ - SH7785 (SH-4A)
+ - DDR2-SDRAM 512MB
+ - NOR Flash 64MB
+ - 2D Graphic controller
+ - SATA controller
+ - Ethernet controller
+ - USB host/peripheral controller
+ - SD controller
+ - I2C controller
+ - RTC
+
+This board has 2 physical memory maps. It can be changed with DIP switch(S2-5).
+
+ phys address | S2-5 = OFF | S2-5 = ON

+ 0x40000000 - 0x5fffffff | DDR SDRAM | (cannot use)
+
+
+This board specific command:
+============================
+
+This board has the following its specific command:
+
+ - hwtest
+ - printmac
+ - setmac
+
+
+1. hwtest
+
+This is self-check command. This command has the following options:
+
+ - all : test all hardware
+ - pld : output PLD version
+ - led : turn on LEDs
+ - dipsw : test DIP switch
+ - sm107 : output SM107 version
+ - net : check RTL8110 ID
+ - sata : check SiI3512 ID
+ - net : output PCI slot device ID
+
+i.e)
+=> hwtest led
+turn on LEDs 3, 5, 7, 9
+turn on LEDs 4, 6, 8, 10
+
+=> hwtest net
+Ethernet OK
+
+
+2. printmac
+
+This command outputs MAC address of this board.
+
+i.e)
+=> printmac
+MAC = 00:00:87:**:**:**
+
+
+3. setmac
+
+This command writes MAC address of this board.
+
+i.e)
+=> setmac 00:00:87:**:**:**
+
