qemu and BE arm64?

[Havard Eidnes <he%NetBSD.org@localhost>]

Hi,

does anyone have a recipe or sketch for how one can spin up a
big-endian NetBSD arm64 VM using qemu, or if that is currently
"difficult"?

My "run a little-endian arm64 system" script currently looks like
this:

#!/bin/sh
SMP=4
MEM=8g
qemu-system-aarch64 -M virt -cpu cortex-a57 -smp $SMP -m $MEM \
  -drive if=none,file=disk.img,id=hd0 -device virtio-blk-device,drive=hd0 \
  -netdev type=user,id=net0,hostfwd=tcp::2222-:22,ipv6=off \
  -nographic \
  -device virtio-net-device,netdev=net0,mac=00:11:66:33:44:55 \
  -device virtio-rng-device \
  -kernel netbsd-GENERIC64.img -append root=ld4a

Regards,
