After booting with u-boot I want replace U-boot binary in NOR flash(EFF80000-EFFFFFFF) with my boot loader and reset the board to boot with my binary but I couldn't do due to NOR flash protection mechanism.

my requirement is like below...

1) boot the board using u-boot

2) replace u-boot with my binary in NOR flash

3) enter "reset" in u-boot console

4) Now when the board boots my binary will be mapped to board should boot with my binary.
