FWIW, I also asked about the Samsung port a few months back and heard no
replies from anyone:

We're also interested in working on Xen support for ARM11 (UP for
now) and ARM in general.

We plan to focus on ARM1136 but will also use ARM926 for development.

Although we were aware of the Ferstay et al paper, we were not aware
that they had that much progress. It's nice to here that they have
already completed their port and hope we all get to see the source soon.

It would be fantastic if Ferstay et al would publish their code! Perhaps
the folks at Xensource would host a Xen ARM HG repository once we have
that code available (although I would personally prefer a GIT repository
myself : ). That may also then encourage more active development and
contributions from others lurking on the list.

Would it be impolite to add Daniel Ferstay to the dist list or did
you already BCC him?
Meanwhile, we're also interested in porting Xen to ARM and would like
to participate in the community porting effort to help get this moving
along out in the open...
