Few notes on booting this as at least Lokesh already hit the mkimage
issue like I did earlier.

To boot this you also need to run mkimage manually on the zImage:

$ mkimage -A arm -O linux -T kernel -C none -a 0x80008000 -e 0x80008000 \
	-n "Linux" -d zImage-omap2plus uImage-omap2plus

And to boot the vexpress on qemu something like this should do:

$ qemu-system-arm -machine vexpress-a9 -m 1024 -net nic -net user -serial stdio \
	-append "console=ttyAMA0,115200n8 rw root=/dev/mmcblk0p2 rootwait" \
	-kernel zImage-omap2plus -initrd initrd.img -sd rootfs.img

I had to build the Linaro qemu to get it to boot, for some reason the
version of qemu in debian unstable did not boot vexpress for me.

Regards,

Tony
