Do you have a dtuart=<something> in your Xen bootargs (in the dtb)?

This is mentioned in
http://wiki.xen.org/wiki/Xen_ARMv7_with_Virtualization_Extensions
but not
http://wiki.xen.org/wiki/Xen_ARMv7_with_Virtualization_Extensions/Arndale

If you are using the dts from Julien's Linux tree it should have this
already, so maybe this is a red herring but I'd have expected the logs
to contain
        "Looking for UART console %s\n", devalias);
from dt_uart_init() and they don't.

I find that the build system is not great at picking up changes to the
DTB, I habitually rm xen/arch/arm/dtb.o before rebuilding Xen.

Ian.
