     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.
     50

     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
    124
