[U-Boot] question on relocation of arm920t

[J.Hwan.Kim]

Hi, everyone

I'm a novice in u-boot.
I have a question about relocation of arm920t.

As far as I know, the relocation code address is defined at config.mk in
board directory.
The code is copied to TEXT_BASE in start.S.
When the u-boot is compiled and linked, it seems that the code address
is set to start at TEXT_BASE.
However, the linker script u-boot.lds tells that code start at 0x00000000.
How does the code address is set to start at TEXT_BASE?
How and where does the linker use TEXT_BASE address?

Thanks in advnace.

Regards,
