For AMD work, I'd try Raptor Engineering:

Hello coreboot people,
we are looking for a hired hand in helping us getting IOMMU (Xen
virtualisation) to work on a APU2c4  - it is a fantastic little AMD SoC
based on AMD GX-412TC and the folks at pcengines did a fantastic job with
it. Philip (zaolin(a)das-labor.org) even got secure boot for it working,
Anyway, we would like to get XEN with IOMMU to work - it is pretty safe to
assume the CPU actually supports it, we are just stuck at weather it is all
related to coreboot, or if there is a bit of a hickup with xen  itself.
I summarised everything we have so far at  - would be great if you
could have a look. In terms of compensation, we are completely open, you
tell us, what works for you, e.g. the usual suspects, or bountysource, etc.
Many thanks!! Jürgen
