-* QEMU Firmware Configuration bindings for ARM
-
-QEMU's arm-softmmu and aarch64-softmmu emulation / virtualization targets
-provide the following Firmware Configuration interface on the "virt" machine
-type:
-
-- A write-only, 16-bit wide selector (or control) register,
-- a read-write, 64-bit wide data register.
-
-QEMU exposes the control and data register to ARM guests as memory mapped
-registers; their location is communicated to the guest's UEFI firmware in the
-DTB that QEMU places at the bottom of the guest's DRAM.
-
-The authoritative guest-side hardware interface documentation to the fw_cfg
-device can be found in "docs/specs/fw_cfg.txt" in the QEMU source tree.
-
-
-Required properties:
-
-- compatible: "qemu,fw-cfg-mmio".
-
-- reg: the MMIO region used by the device.
-  * Bytes 0x0 to 0x7 cover the data register.
-  * Bytes 0x8 to 0x9 cover the selector register.
-  * Further registers may be appended to the region in case of future interface
-    revisions / feature bits.
-
-Example:
-
-/ {
-	#size-cells = <0x2>;
-	#address-cells = <0x2>;
-
-	fw-cfg@9020000 {
-		compatible = "qemu,fw-cfg-mmio";
-		reg = <0x0 0x9020000 0x0 0xa>;
-	};
-};
