Hi; I'm moving this bug to 'incomplete', because I was never able to
repro it -- gtk and sdl displays both worked for me.

Title:
qemu-system-aarch64 shows black framebuffer window on minimal bare
metal example on SDL but not on VNC
Status in QEMU:
Incomplete
Bug description:
QEMU v2.12.0, Ubuntu 18.04 host.
Build QEMU and the bare metal image exactly as described at:
https://raspberrypi.stackexchange.com/revisions/85135/4 with:
Then cd into example 09_framebuffer.
Now if I do:
../../qemu/aarch64-softmmu/qemu-system-aarch64 -M raspi3 -kernel
kernel8.img -serial stdio
the SDL window shows up black.
However, if I use VNC:
../../qemu/aarch64-softmmu/qemu-system-aarch64 -M raspi3 -kernel kernel8.img
-serial stdio -vnc :1
vinagre :5901
an image of Homer Simpson appears as expected.
Therefore, I think this must be a QEMU / SDL bug instead of the
repository, since we get different behaviors with `-vnc` and with SDL.
