That depends on what bootloader we're talking about -- I don't know
what the original poster's custom loader can do. Obviously the
bootloader itself would have to be executing from some other address
(e.g. U-Boot runs from the top of RAM).

Yes, of course. But that's a different issue. :-)

I was just using our hypervisor as an example, since it has an ELF
loader that can pass a device tree.

The guest OS *is* the same as native Linux, as far as TLB handling is
