No, we cannot. This string is not used anywhere in the whole U-Boot source code.

I guess you mean TEXT_BASE TEXT_BASE is the base address for U-boot code in flash memory.

I'm not sure. He ased about BOOT_TEXT_BASE

TEXT_BASE is the base address for U-boot code in flash memory.

This may be correct on PowerPC systems, but on other architectres this is NOT correct.

on ARM architectures TEXT_BASE specifies the address for which U-Boot is linked. After power up the U-Boot startup code copies (not relocates) U-Boot to this address. Thus, the address should lie in RAM. The startup code itself is address independent.
