Breno Matheus Lima 656d8da9d2 doc: Remove duplicated documentation directory
Commit ad7061ed74 ("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>;
rxaui1 = <&RXAUI1>;
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>;
/* MC2/SC-Board */
var-gpios-mc2 = <&GPIO_VB0 0 0 /* VAR-MC_SC */
&GPIO_VB0 11 0>; /* VAR-CON */
/* MC4-Board */
var-gpios-mc4 = <&GPIO_VB1 0 0 /* VAR-MC_SC */
&GPIO_VB1 11 0>; /* VAR-CON */
reset-gpios = <&gpio0 1 0 &gpio0 2 1>;
};
