Why?

Do you think on devices with 128 MB flash memory  we  should  have  a
128MB U-Boot image?

Do you see any problem with having a U-Boot image that is smaller than
your flash device?

Agreed.

That's your problem, tehn. Most people use a noremal JTAG debugger
which can prgram the image to any address in the flash.

You got to add 256k of ramdom data in front of the 256 k image,  then
[memory filled with 0xFF recommended].
