[U-Boot-Users] timeout while waiting for opcode fetch?

[zhuzhenhua]

when i do reset and then go in BDI2000, sometimes the seial_puts in
board_init_r output corretly, sometimes not.

 if output correctly, i can type halt in BDI2000  to see it's info
but if not output correctly, type halt it will give these strings in BDI2000
