>Description:

Trying to boot a aarch64 big endian image on QEMU, nearly identical to 
the instrucstions in the wiki at

https://wiki.netbsd.org/ports/evbarm/qemu_arm/

with the QEMU_EFI.fd for arm64 linked there (but I used the latest
available newer version 5552).

Running

qemu-system-aarch64 -M virt -cpu cortex-a53 -smp 4 -m 4g \
    -drive if=none,file=arm64be.img,id=hd0 -device virtio-blk-device,drive=hd0 \
    -netdev type=user,id=net0 -device \
	virtio-net-device,netdev=net0,mac=00:11:22:33:44:55 \
    -bios QEMU_EFI.fd \
    -device virtio-rng-pci \
    -device virtio-gpu -nographic


gives me:

  \\-__,------,___.
   \\        __,---`  NetBSD/evbarm efiboot (arm64)
    \\       `---,_.  Revision 2.15 (Sat Jul 26 13:28:13 UTC 2025)
     \\-,_____,.---`
      \\
       \\
        \\

Press return to boot now, any other key for boot prompt
booting netbsd - starting in 0 seconds.
