If you give -kernel on ARM (non-M-profile) systems something
that isn't an ELF file this means "I am a Linux kernel and
want the calling convention documented for the kernel" (which
includes that load address, among other things). If you're
not a Linux kernel then don't do that.

You probably want the "-device loader" documented in
docs/generic-loader.txt, which is (as the name suggests)
a generic way to load an arbitrary binary into memory,
and lets you specify whatever load address you want.
