I was able to get qemuarma9 to work with the latest oe-core master
and the linux-yocto-3.10 kernel using standard/base branch.

I built the rootfs using yocto, but manually compiled the kernel separately.

I had to enable devtmpfs in the defconfig and have attached it below.

I used the following command to launch qemu, manually.

qemu-system-arm -M vexpress-a9 -m 1024 -kernel \
/project/kernel/linux-yocto-3.10/arch/arm/boot/zImage -sd \
/tool/yocto/poky/build/tmp/deploy/images/core-image-minimal-qemuarma9.ext3 -append \
"console=tty1 mem=1024M root=/dev/mmcblk0 rw"
