[Xen-devel] [PATCH] [PATCH v4] Fetch the OVMF repository from specific git mirror and enable it

[Attilio Rao <attilio.rao@xxxxxxxxxx>]

Signed-off-by: Attilio Rao <attilio.rao@xxxxxxxxxx>

Changed since v3:
- Only enabled on Linux as OVMF does not build yet on BSD flavours
- Added subdir-clean-ovmf
- The Linux build may be busted for userland compiled as i486, i586 and
  i786. The following OVMF fix, not yet upstreamed, should fix this:
