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

  68 This board specific command:
  69 ============================
  70
  71 This board has the following its specific command:
  72
  73  - hwtest
  74  - printmac
  75  - setmac
  76  - pmb (sh7785lcr_32bit_config only)
  77
  78
  79 1. hwtest
  80
  81 This 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
  92 i.e)
  93 => hwtest led
  94 turn on LEDs 3, 5, 7, 9
  95 turn on LEDs 4, 6, 8, 10
  96
  97 => hwtest net
  98 Ethernet OK
  99
 100
 101 2. printmac
 102
 103 This command outputs MAC address of this board.
 104
 105 i.e)
 106 => printmac
 107 MAC = 00:00:87:**:**:**
 108
 109
 110 3. setmac
 111
 112 This command writes MAC address of this board.
 113
 114 i.e)
 115 => setmac 00:00:87:**:**:**
 116
 117
 118 4. pmb
 119
 120 This command change PMB for DDR-SDRAM all mapping. However you cannot use
 121 NOR Flash and USB Host on U-Boot when you run this command.
 122 i.e)
 123 => pmb
