It is very limited only serial is supported right now. Patches 1-4 can be applied independently. Patch 5 may need some more attention since Ahmad told me in person that not all softcores implementing the vendorid register. Please see the patch notes on this patch. Patch 6 adds the support for the D1 board and a detailed description how to build and flash a bootable image.
