my problem To make U-Boot a 2nd stage boot loader, I mean a seperate boot loader (stage #1) loader U-Boot from flash into SDRAM.
Well, in your first posting you said you were using the Atmel AT91RM9200DK board, and that it already boots the way you described? What is it that you want to change?
Since it mainly concerns with the linker, no source code need modification if it use no linker script defined staff. In this case, if U-Boot do not use the TEXT_BASE in source code, there will be no change to the source code. That's my idea.
TEXT_BASE is used in several places in the source tree; for starters, see cpu/arm920t/at91rm9200/lowlevel_init.S and cpu/arm920t/start.S
