+gdsys Gazerbeam board driver
+
+This driver provides capabilities to access the gdsys Gazerbeam board's device
+information. Furthermore, phandles to some internal devices are provided for
+the board files.
+
+Required properties:
+- compatible:  should be "gdsys,board_gazerbeam"
+- csb:         phandle to the board's coherent system bus (CSB) device node
+- rxaui[0-3]:  phandles to the rxaui control device nodes
+- fpga[0-1]:   phandles to the board's gdsys FPGA device nodes
+- ioep[0-1]:   phandles to the board's IO endpoint device nodes
+- ver-gpios:   GPIO list to read the hardware version from
+- var-gpios:   GPIO list to read the hardware variant information from
+- reset-gpios: GPIO list for the board's reset GPIOs
+
+Example:
+
+

+	compatible = "gdsys,board_gazerbeam";
