161	ARM Versatile Express Boards
162	-----------------------------
163	For details on the device tree bindings for ARM Versatile Express boards
164	please consult the vexpress.txt file in the same directory as this file.
165	
166	ARM Juno Boards
167	----------------
168	The Juno boards are targeting development for AArch64 systems. The first
169	iteration, Juno r0, is a vehicle for evaluating big.LITTLE on AArch64,
170	with the second iteration, Juno r1, mainly aimed at development of PCIe
171	based systems. Juno r1 also has support for AXI masters placed on the TLX
172	connectors to join the coherency domain.
173	
174	Juno boards are described in a similar way to ARM Versatile Express boards,
175	with the motherboard part of the hardware being described in a separate file
176	to highlight the fact that is part of the support infrastructure for the SoC.
177	Juno device tree bindings also share the Versatile Express bindings as
178	described under the RS1 memory mapping.
179	
180	Required properties (in root node):
181		compatible = "arm,juno";	/* For Juno r0 board */
182		compatible = "arm,juno-r1";	/* For Juno r1 board */
183	
184	Required nodes:
185	The description for the board must include:
186	   - a "psci" node describing the boot method used for the secondary CPUs.
187	     A detailed description of the bindings used for "psci" nodes is present
188	     in the psci.txt file.
189	   - a "cpus" node describing the available cores and their associated
190	     "enable-method"s. For more details see cpus.txt file.
191	
192	Example:
193	
194	/dts-v1/;
195	/ {
196		model = "ARM Juno development board (r0)";
197		compatible = "arm,juno", "arm,vexpress";
198		interrupt-parent = <&gic>;
199		#address-cells = <2>;
200		#size-cells = <2>;

203			#address-cells = <2>;
204			#size-cells = <0>;
205	
206			A57_0: cpu@0 {
207				compatible = "arm,cortex-a57","arm,armv8";
208				reg = <0x0 0x0>;
209				device_type = "cpu";
210				enable-method = "psci";
211			};
212	
213			.....

215			A53_0: cpu@100 {
216				compatible = "arm,cortex-a53","arm,armv8";
217				reg = <0x0 0x100>;
