Ah, I think I see it now. We can't use 0x0 as where to load stuff to
and the tests default to 0x0 if you don't provide an address rather than
$loadaddr. I'll see about changing the tests.

So this one is interesting. I see the same failure for MIPS/PPC for the
qemu targets we have as well. I don't see this under QEMU for the ARM
targets that I'm emulating. I suspect there's some common problem on
the U-Boot side as also don't see this on the VMs I have running under
qemu nor when I boot the kernelci rootfs from U-Boot.
