-ARM Versatile Express Boards
------------------------------
-For details on the device tree bindings for ARM Versatile Express boards
-please consult the vexpress.txt file in the same directory as this file.
-
-ARM Juno Boards
-----------------
-The Juno boards are targeting development for AArch64 systems. The first
-iteration, Juno r0, is a vehicle for evaluating big.LITTLE on AArch64,
-with the second iteration, Juno r1, mainly aimed at development of PCIe
-based systems. Juno r1 also has support for AXI masters placed on the TLX
-connectors to join the coherency domain.
-
-Juno boards are described in a similar way to ARM Versatile Express boards,
-with the motherboard part of the hardware being described in a separate file
-to highlight the fact that is part of the support infrastructure for the SoC.
-Juno device tree bindings also share the Versatile Express bindings as
-described under the RS1 memory mapping.
-
-Required properties (in root node):
- compatible = "arm,juno"; /* For Juno r0 board */
- compatible = "arm,juno-r1"; /* For Juno r1 board */
- compatible = "arm,juno-r2"; /* For Juno r2 board */
-
-Required nodes:
-The description for the board must include:
- - a "psci" node describing the boot method used for the secondary CPUs.
- A detailed description of the bindings used for "psci" nodes is present
- in the psci.yaml file.
- - a "cpus" node describing the available cores and their associated
- "enable-method"s. For more details see cpus.yaml file.
-
-Example:
-
-/dts-v1/;
-/ {
- model = "ARM Juno development board (r0)";
- compatible = "arm,juno", "arm,vexpress";
- interrupt-parent = <&gic>;
- #address-cells = <2>;
- #size-cells = <2>;
-
- cpus {
- #address-cells = <2>;
- #size-cells = <0>;

- compatible = "arm,cortex-a57";
- reg = <0x0 0x0>;
- device_type = "cpu";
- enable-method = "psci";
- };
-
- .....
-
- A53_0: cpu@100 {
- compatible = "arm,cortex-a53";
- reg = <0x0 0x100>;
- device_type = "cpu";
