Yes it helped and I got a bit further, but had to make the following
changes:

  - Move the u-boot tag to v2013.10 (rather than the RC), as Xen
    complained that it must enter the CPU in NS Hyp mode. Clearly RC
    wasn't doing that.

  - Xen was attempting to bring up CPU 2 and stalling there. But I
    believe the idea was to leave A7s in reset and use only 2 A15s. So I
    had to remove the Cortex A7 CPUs from the Linux DTS, and use the DTB
    from there

With those changes, I see Xen going further but hits a data abort. Logs
attached; I'll see if I can dig further.

Meanwhile, if you think the changes I made as above are valid, could you
update the Wiki to reflect them?
