Speaking of the real hardware QEMU is emulating...
The a9 vexpress has a 'CLCD' display, and it looks like QEMU supports
that: https://wiki.linaro.org/PeterMaydell/QemuVersatileExpress
For the a15-tc1 vexpress, that has a 'HDLCD' display and that quite
probably isn't emulated.
Actually, the vexpress hardware consists of a CPU CoreTile (a9, a15-tc1,
etc) plugged into a motherboard, and the motherboard also has it's own
display of the 'CLCD' type, don't know how much of that setup QEMU
emulates. So, it's possible that removing HDLCD from the a15-tc1
device-tree and leaving the CLCD of the motherboard might get that
working.
