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 AXI busses of IHS FPGA devices
+
+Certain gdsys IHS FPGAs offer a interface to their built-in AXI bus with which
+the connected devices (usually IP cores) can be controlled via software.
+
+Required properties:
+- compatible: must be "gdsys,ihs_axi"
+- reg: describes the address and length of the AXI bus's register map (within
+ the FPGA's register space)
+
+Example:
+
+fpga0_axi_video0 {
+ #address-cells = <1>;
+ #size-cells = <1>;
+ compatible = "gdsys,ihs_axi";
+ reg = <0x170 0x10>;
+
+ axi_dev_1 {
+ ...
+ };
+};
