171	ARM Versatile Express Boards
172	-----------------------------
173	For details on the device tree bindings for ARM Versatile Express boards
174	please consult the vexpress.txt file in the same directory as this file.
175	
176	ARM Juno Boards
177	----------------
178	The Juno boards are targeting development for AArch64 systems. The first
179	iteration, Juno r0, is a vehicle for evaluating big.LITTLE on AArch64,
180	with the second iteration, Juno r1, mainly aimed at development of PCIe
181	based systems. Juno r1 also has support for AXI masters placed on the TLX
182	connectors to join the coherency domain.
183	
184	Juno boards are described in a similar way to ARM Versatile Express boards,
185	with the motherboard part of the hardware being described in a separate file
186	to highlight the fact that is part of the support infrastructure for the SoC.
187	Juno device tree bindings also share the Versatile Express bindings as
188	described under the RS1 memory mapping.
189	
190	Required properties (in root node):
191		compatible = "arm,juno";	/* For Juno r0 board */
192		compatible = "arm,juno-r1";	/* For Juno r1 board */
193		compatible = "arm,juno-r2";	/* For Juno r2 board */
194	
195	Required nodes:
196	The description for the board must include:
197	   - a "psci" node describing the boot method used for the secondary CPUs.
198	     A detailed description of the bindings used for "psci" nodes is present
199	     in the psci.txt file.
200	   - a "cpus" node describing the available cores and their associated
201	     "enable-method"s. For more details see cpus.txt file.
202	
203	Example:
204	
205	/dts-v1/;
206	/ {
