Well, it is not used by U-Boot itself, but when you have a big  Linux
kernel it starts overwriting itself when you uncompress it to address
0.

U-Boot does not know the uncompressed size in advance. And  anyway  -
it's  a  pilot  error  :-)  In modification of anmother famous quote:
"U-Boot was not designed  to  stop  you  from  doing  stupid  things,
because that would also stop you from doing clever things."
