[U-Boot] Problem to link u-boot for sh2a 7203

Hi All, I can compile u-boot for rsk7203_config. But into the file board/renesas/rsk7203/config.mk

TEXT_BASE = 0x0C7C0000

and if I read u-boot.srec that is the result of building process I see that the address spce of the code is starting from 0x0C7C0000

On my board I have 32 bit SDRAM at such an address, and even if I could uxecute the program using an emulator initializing in place of me the BSC, how can I flash at 0x00000000 (start address of NOR flash) my bootloader? How can I link the loader so that I can flash the code into my NOR flash and using a part of SDRAM I have to run the bootloader?

Thanks in advance.
