No, CONFIG_SYS_TEXT_BASE is NOT the relocation address. The relocation
address gets dynamically computed and may vary. CONFIG_SYS_TEXT_BASE
is the base address of the text segment when linking the U-Boot
image.

As the name attempts to suggest, CONFIG_SYS_INIT_SP_ADDR defines the
address of the initial steck pointer in the restricted C runtime
environment before relocation.

Read the documentation and especially existing code for other, similar
