+
+configuration for This board:
+=============================
+
+You can choose configuration as follows:
+
+ - make sh7785lcr_config
+ - make sh7785lcr_32bit_config
+
+When you use "make sh7785lcr_config", there is build U-Boot for 29-bit
+address mode. This mode can use 128MB DDR-SDRAM.
+
+When you use "make sh7785lcr_32bit_config", there is build U-Boot for 32-bit
+extended address mode. This mode can use 384MB DDR-SDRAM. And if you run
+"pmb" command, this mode can use 512MB DDR-SDRAM.
+

+
+This board specific command:
+============================
+
+This board has the following its specific command:
+
+ - hwtest
+ - printmac
+ - setmac
+ - pmb (sh7785lcr_32bit_config only)
+
+
+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:**:**:**
+
+
+4. pmb
+
+This command change PMB for DDR-SDRAM all mapping. However you cannot use
+NOR Flash and USB Host on U-Boot when you run this command.
+i.e)
+=> pmb
