0x800 works fine, but honestly I don't know why Peter P ages ago chose the
very odd address 0x7fc0.

But you know U-boot way better than me, and most things work fine it seems.
What is a typical load address?

Not really, it was mainly because there is no way to set the FDT load
address as a variable, e.g. we don't have CONFIG_FDT_LOAD_ADDR,
and I wanted to keep both definitions in the same place, i.e. in the
default boot script.

On the Integrator/AP I have to load the two pieces one at the time,
manually using loady, so it is a bit helpful to have the address prints
at least.
