Yes, for a long time the MMU emulation was half done. A few months ago
I pushed a set of patches to add enough MMU emulation to handle linux
guests. But there are still parts missing.
The virtex-ml507 board works good enough to run linux on. I can dig
for kernel configs and publish devicetrees and kernel images if
there is interest.
