The xenvm-4.2.dts only works with Versatile Expresss, because the gic is not
mapped to the right address.

I have pushed a working tree for domU based on linux 3.9-rc3:
http://xenbits.xen.org/gitweb/?p=people/julieng/linux-arm.git;a=shortlog;h=refs/heads/arndale-domU-3.9

You can compile with:
make ARCH=arm xen_domU_arndale_defconfig
make ARCH=arm zImage

And the you just need to append the dts.

Cheers,

Julien
