Hello again.

I have made progress. It looks like efi_vars was missing. I added
empty 64MB img file as second pflash and then it booted to console
line.
My qemu cmd line looks like:
qemu-system-aarch64.exe -M virt -m 1G -cpu cortex-a57 -pflash
edk2-aarch64-code.fd -pflash efi_vars.img -cdrom
alpine-virt-3.11.2-aarch64.iso -vga none -device
virtio-gpu-pci,xres=800,yres=600 -net nic,model=virtio -net
user,hostfwd=tcp::2222-:22 -device usb-ehci,id=ehci -device
usb-tablet,bus=ehci.0
.
Then I can successfully login on serial console. Other problem is that
on graphic console (virtio-gpu-pci) the keyboard is not working
eventhough I have added usb-tablet. But that's another story. I was
not able to get keyboard and mouse with virtio-gpu-pci on any
distribution I have tried. Maybe some qemu command line parameter is
missing.

So now I can boot and ISO is working.
