doc: Remove duplicated documentation directory
Commit ad7061ed742e ("doc: Move device tree bindings documentation to doc/device-tree-bindings") moved all device tree binding documentation to doc/device-tree-bindings directory. The current U-Boot project still have two documentation directories: - doc/ - Documentation/ Move all documentation and sphinx files to doc directory so all content can be in a common place.

+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:
+
+
+board {
+ compatible = "gdsys,board_gazerbeam";
+ csb = <&board_soc>;
+ serdes = <&SERDES>;
+ rxaui0 = <&RXAUI0>;

+ rxaui2 = <&RXAUI2>;
+ rxaui3 = <&RXAUI3>;
+ fpga0 = <&FPGA0>;
+ fpga1 = <&FPGA1>;
+ ioep0 = <&IOEP0>;
+ ioep1 = <&IOEP1>;
+
+ ver-gpios = <&PPCPCA 12 0
+ &PPCPCA 13 0
+ &PPCPCA 14 0
+ &PPCPCA 15 0>;
