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.

68This board specific command:
69============================
70
71This board has the following its specific command:
72
73 - hwtest
74 - printmac
75 - setmac
76 - pmb (sh7785lcr_32bit_config only)
77
78
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
96
97=> hwtest net
98Ethernet OK
99
100
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.
122i.e)
123=> pmb
