I tried to test this device using the 'eng' branch of
git://git.linux-mips.org/pub/scm/linux-mti.git and using the
'64r2el_defconfig' config but I get:

qemu-system-mips64el: Unable to copy device tree in memory
unable to load FIT image

I noticed the PPC machines use the _FDT() macro (see "hw/ppc/fdt.h") to
eventually give more useful error message.
