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.
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.
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.
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 */
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.
