My board need keep the first 0x40000 flash for special purpose. Is it
easy to modify the u-boot to load itself from 0x40000 instead from the
0x0000? Any help is appreciated.

It's not U-Boot code what determines the boot address, but your
processor. So your real question is if you can teach your CPU to
start from a different reset vector. But sorry, we cannot answer this
here.

Thought for the day: What if there were no hypothetical situations?

If your hardware supports it, probably. Otherwise no. Perhaps you
could tell us what your hardware is?
