What you describe may be how it works for PPC platforms but not for ARM.

For the ARM platforms, TEXT_BASE is the location of U-Boot in RAM.  You 
program the binary to the location your cpu executes on reset...the start of 
a flash bank.  This is for the few arm920 based SoCs I've worked on or seen.
