I used qemu_arm64_lwip_defconfig
qemu-system-aarch64 -m 1024 -smp 2 -nographic -cpu cortex-a57 \
-machine virt,secure=off -bios u-boot.bin -chardev
socket,id=chrtpm,path=/tmp/mytpm1/swtpm-sock \
-tpmdev emulator,id=tpm0,chardev=chrtpm -device
tpm-tis-device,tpmdev=tpm0 \
-device virtio-rng-pci -drive
id=os,if=none,file=../debian.qcow2 -device virtio-blk-device,drive=os
is the command line
