What do you mean "flash the E3"? Are you writing your kernel into the

Generally you use pbltool to load whatever kernel image you've made to
0x11d00000. You then do "bootm 11d00000" in u-boot, which relocates the
kernel to the appropriate kernel load address and executes it. As such
there are 2 "load addresses"; one for where pbltool loads the kernel and
one for where u-boot loads it to. Which are you talking about?
