[Xen-devel] [PATCH] Fetch the OVMF repository from specific git mirror and enable it

[Attilio Rao <attilio.rao@xxxxxxxxxx>]

- Fetch the OVMF parent tree from: http://github.com/tianocore/edk2.git
- Add a simple Makefile to edk2 that automagically runs the right scripts
  to build OVMF and setles the resulting binary properly
