Gustavo Zacarias c06ec1e397 configs/qemu: update arm-vexpress instructions for SMP
We can use the vexpress arm defconfig to test SMP features in Qemu.
So document the necessary invocation changes to account for this, in
preparation of the arm nuri defconfig removal.

Run the emulation with:

  qemu-system-arm -M vexpress-a9 -smp 1 -m 256 -kernel output/images/zImage -dtb output/images/vexpress-v2p-ca9.dtb -drive file=output/images/rootfs.ext2,if=sd,format=raw -append "console=ttyAMA0,115200 root=/dev/mmcblk0" -serial stdio -net nic,model=lan9118 -net user

The login prompt will appear in the terminal that started Qemu. The
graphical window is the framebuffer.

If you want to emulate more cores change "-smp 1" to "-smp 2" for
dual-core or even "smp -4" for a quad-core configuration.

Tested with QEMU 2.3.0
