	  This option enables generic support for Xilinx Virtex based boards

	  that use a 440 based processor in the Virtex 5 FXT FPGA architecture.



	  The generic virtex board support matches any device tree which

	  specifies 'xlnx,virtex440' in its compatible field.  This includes

	  the Xilinx ML5xx reference designs using the powerpc core.



	  Most Virtex 5 designs should use this unless it needs to do some

	  special configuration at board probe time.
