Yep, it does:
000a9000: 00 1c 04 00 00 00 1d 0a 78 69 6c 69 6e 78 5f 73 ........xilinx_s
000a9010: 70 69 00 00 00 00 00 00 00 03 00 00 00 00 00 00 pi..............
that's from:
./arm-softmmu/qemu-system-arm -M tosa -device at26f004 -S -nographic
QEMU 2.6.90 monitor - type 'help' for more information
(qemu) migrate "exec:xxd -g 1 > tosa.mig"
it's not essential to redo the version_id's, but it's as good a time as any
to get rid of the old version code if you've just broken the compatibility
anyway.
