It looks like the HVC driver is enabled, and I've included the output of both "q" and "0" below as well as my u-boot version and parameters. It might be helpful if someone could chime in with the versions (Xen and kernel) that have been shown to boot successfully. I bring this up because the FTD patch didn't apply cleanly against any of the kernels that I tried, so I ended up manually applying the patch. best, JP u-boot parameters: U-Boot 2013.01-gdc6238c (Mar 27 2013 -
