No. TEXT_BASE is an absolute address.

On architectures like ARM (where the implementation is based on a
broken concept of the system memory map) TEXT_BASE should always be
chosen to be as high as possible to put the ("relocated") U-Boot code
as close as possible to the very end of available RAM.  For systems
with several RAM size options you have to set this according to the
smallest possible RAM size, of course (which is a major PITA).
