0x0c000000 - 0x0fffffff(CS3) | SD | DDR SDRAM
0x10000000 - 0x13ffffff(CS4) | SM107 | SM107
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.

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
