Sorry about that, I just hit the replay button and didn't realized that the answer went directly to you instead to the mailing list.
Generally, they can share the same value, but they have different meaning. For TX25, the link address is set in board/karo/tx25/config.mk. However, this is the old way to do things. Currently, CONFIG_SYS_TEXT_BASE (link address) must be set into the board configuration file (tx25.h). CONFIG_SYS_NAND_U_BOOT_DST tells the first loader (nand_spl) where u-boot code must be copied. If u-boot has a small header that must be also copied, the two address are different. On tx25, they have the same value.
Thank you very much for your explanation. I'd like to learn how u-boot works and how a board support package have to be implemented. Probably I'd better choose another board if the BSP of the TX25 uses some deprecated ways.
Best regards, Martin
