[U-Boot-Users] I cann't initialize OR/BR registers in cpu_init.c?

[wang cheng]

hello !
   all
   I'm porting u-boot-0.4.0 to my WindRiver MDP PRO board now,some 
addressing specifications are listed below.I choose the 

fads823 as the model.I have vision ICE ii & vision CLICK to program 
flash and debug the code.
   I compile the code in the vmware linux environment.After "make 
myboard_config" and  "make",I copy the u-boot(ELF) to the 

vision CLICK path in windows environment，then Convert to .BIN file, 
program to  flash,run,use the hyperterminal  as the 

console.
   Now in the cpu_init.c ,I masked all the OR/BR initialization 
clause,for when I released them there's nothing displayed on 

the hyperterminal ;but when masked them ,the program can run to 
the "=>"(after main_loop();)with the vision ICE II and to the 

relocate_code()(in the board_init_f();)without the visionICE II ,some 
register value are listed below in the vision CLICK BKM 

mode.

**1.why I cann't initialize the OR/BR registers in the cpu_init.c
**2.how to modify the dram initialization to pass the relocate_code()
3.can you tell me something details about the BCSR register in the 
FADS823 model.
4.are there any better model for WindRiver MDPRRO board ?
 
Any suggests are very appreciated!

specifications:
Addressing:
Total address range	4GB (on and off board)
Flash Memory 		1.0MB on board
			16MB SIMM (4MB Std.)
SRAM Memory 		2MB (512K Std.)
