First, U-Boot 1.1.6 is more than 5 years old and only of interest to
paleontologists - like a dinosaur.  I tmakes absolutely no sense
putting any efforts n such old code.  Please do yourself (and us) a
favour and use current code (i. e. v2011-06-rc3 or later).

Then just change the setting of TEXT_BASE as needed.

Note that it would have been helpful if you had mentioned which
architecture / CPU / board you are talking about.

Best regards,
