Is there support for LEON4 SPARC v8-compatible CPU

[Tito Mari Francis Escaño]

Good day,
I checked http://www.openbsd.org/sparc.html and found no explicit support
for LEON4: http://www.gaisler.com/index.php/products/boards/gr-leon4-itx. I
plan to inquire and hopefully get this board as gift in the last quarter of
this year, but it doesn't seem to be explicitly supported. I googled and
found only reference for Linux kernel-related works with this CPU and
board. Can you please provide me pointers on the support status of this CPU
and board.
Thank you very much.
