I forgot to mention that for the DTB I am using
arch/arm/boot/dts/vexpress-v2p-ca15-tc1.dtb built by the kernel tree,
passing it to the Xen build on the make command line:
        make -C xen XEN_TARGET_ARCH=arm64
        CONFIG_DTB_FILE=/home/ianc/vexpress-v2p-ca15-tc1-linux.dtb
        debug=y CROSS_COMPILE=aarch64-linux-gnu- -j12 -s install

Xen is passed to the model directly as the image to boot (no
bootwrapper)

The dom0 kernel is passed to the hypervisor in the flash "-C
motherboard.flashloader0.fname=zImage". The arm64 boot-wrapper is not
yet advanced enough to be ported to the scheme used in "xen: arm: parse
modules from DT during early boot." per
http://lists.xen.org/archives/html/xen-devel/2013-01/msg02469.html

For the guest I use arch/arm/boot/xenvm-4.2.dtb and append it to the
zImage (the kernel config has CONFIG_ARM_APPENDED_DTB).
Ian.
