  36configuration for This board:
  37=============================
  38
  39You can choose configuration as follows:
  40
  41 - make sh7785lcr_config
  42 - make sh7785lcr_32bit_config
  43
  44When you use "make sh7785lcr_config", there is build U-Boot for 29-bit
  45address mode. This mode can use 128MB DDR-SDRAM.
  46
  47When you use "make sh7785lcr_32bit_config", there is build U-Boot for 32-bit
  48extended address mode. This mode can use 384MB DDR-SDRAM. And if you run
  49"pmb" command, this mode can use 512MB DDR-SDRAM.

  71This board has the following its specific command:
  72
  73 - hwtest
  74 - printmac
  75 - setmac
  76 - pmb (sh7785lcr_32bit_config only)
  77

  791. hwtest
  80
  81This is self-check command. This command has the following options:
  82
  83 - all          : test all hardware
  84 - pld          : output PLD version
  85 - led          : turn on LEDs
  86 - dipsw        : test DIP switch
  87 - sm107        : output SM107 version
  88 - net          : check RTL8110 ID
  89 - sata         : check SiI3512 ID
  90 - net          : output PCI slot device ID
  91
  92i.e)
  93=> hwtest led
  94turn on LEDs 3, 5, 7, 9
  95turn on LEDs 4, 6, 8, 10

 1012. printmac
 102
 103This command outputs MAC address of this board.
 104
 105i.e)
 106=> printmac
 107MAC = 00:00:87:**:**:**
 108
 109
 1103. setmac
 111
 112This command writes MAC address of this board.
 113
 114i.e)
 115=> setmac 00:00:87:**:**:**
 116
 117
 1184. pmb
 119
 120This command change PMB for DDR-SDRAM all mapping. However you cannot use
 121NOR Flash and USB Host on U-Boot when you run this command.
