You cannot run the image without buring it to flash.

Did you bother to read the FAQ?  The very first U-Boot FAQ handles
your situation:

You may be able to istall a NAND booting version of U-Boot to NAND
flash (assuming your out-of-tree port supports NAND booting).

Once you got this working, you have a recovery system, and you can
erase and re-program the NOR flash without risk.

Best regards,

Wolfgang Denk

There are two ways of constructing a software design. One way  is  to
make  it  so  simple that there are obviously no deficiencies and the
other is to make it so complicated that there are  no  obvious  defi-
ciencies.                             - Charles Anthony Richard Hoare
