* [PATCHv2 4/4] Virtex: Add generic Xilinx Virtex board support
From: Grant Likely @ 2007-09-30 22:20 UTC (permalink / raw)
  To: linuxppc-dev, jwboyer
In-Reply-To: <20070930221613.583.252.stgit@trillian.cg.shawcable.net>

From: Grant Likely <grant.likely@secretlab.ca>

Adds support for generic Xilinx Virtex boards.  Any board which specifies
"xilinx,virtex" in the compatible property will make use of this board
support.
