========================================

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
 -------------------------------+---------------+---------------
 0x00000000 - 0x03ffffff(CS0)	| NOR Flash	| NOR Flash
 0x04000000 - 0x05ffffff(CS1)	| PLD		| PLD
 0x06000000 - 0x07ffffff(CS1)	| reserved	| I2C
 0x08000000 - 0x0bffffff(CS2)	| USB		| DDR SDRAM
 0x0c000000 - 0x0fffffff(CS3)	| SD		| DDR SDRAM

 0x14000000 - 0x17ffffff(CS5)	| I2C		| USB
 0x18000000 - 0x1bffffff(CS6)	| reserved	| SD
 0x40000000 - 0x5fffffff	| DDR SDRAM	| (cannot use)


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.

 * 32-bit extended address mode PMB mapping *

   -------------+---------------+---------------+---------------
   0x88000000	| 0x48000000	| 384MB		| DDR-SDRAM (Cacheable)

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
