[U-Boot-Users] u-boot porting problem

[dune summer]

I'm porting u-boot 1.1.4 to my custom MPC8541 board,
The resource on my board is like this:
  LCS0  Boot flash                0xFFF8_0000-0xFFFF_FFFF 512KB
CCSR Default Value           0xFF70_0000-0xFF7F_FFFF 1MB
LCS1  NvRAM                   0xFF6E_0000-0xFF6F_FFFF 128KB
          CPLD                     0xFF60_0000-0xFF67_FFFF 512KB
LCS2  Image Flash1          0xF400_0000-0xF5FF_FFFF 32MB
LCS3  Image Flash2          0xF600_0000-0xF7FF_FFFF 32MB
CS1   discret DDR Bank1   0x0000_0000-0x07FF_FFFF 128MB
CS0   discret DDR Bank0   0x0800_0000-0x0FFF_FFFF 128MB
          PCI memory space   0x8000_0000-0x9000_0000 512MB
  Because my board have no SPD_EEPROM for DDR config,so I choose MPC8560ads 
board as template.
First I change the init.S file,rearrange the TLB entry according to my board,
then I change include/configs/mpc8560ads.h according to my board,
then compile and burn the u-boot.bin into boot flash.
After power on,there have nothing dump from console.
  I have freescale codewarrior and USBTAP by my hand,so I debug the u-boot with CodeWarrior
and I found that the program fly away from start.S->inflash:->bl cpu_init_f.
  Anybody who can help me to resolve this problem? And any suggestion should be appreciated.
  By the way,is there any other method to debug u-boot before console dump on mpc85xx,such
as light led on GPIO pin?
  I think CodeWarrior is hard to use,could anybody use it successfully can share me some useful
experience.
  I'm not familar with PPC assemble language,anyone can tell me what's the meaning ".long" 
in this sentence?
  .long TLB1_MAS0(0, 0, 0)
  Thanks.
