vgic dump printed ID not SPI. I have just noticed that my current branch (based
on linux upstream 3.9-rc4) doesn't support exynos ATA.
It seems the driver is not yet upstreamed in the kernel.

I have updated my tree with a branch based on linaro's tree (which is
a linux 3.10-rc2)
and there is a driver for the exynos ATA. The command to clone and compile the
kernel:

git clone -b linaro-3.10
git://xenbits.xen.org/people/julieng/linux-arm.git linux
cd linux
make arndale_xen_dom0_defconfig
make zImage
make dtbs

The device tree is: arch/arm/boot/dts/exynos5250-arndale.dtb

If it works for you I will update the wiki page and stick to the linaro tree for
the next update.

Cheers,
