From 3f173071bf1401bfb092fe67f43caf3bc358da03 Mon Sep 17 00:00:00 2001 From: Radha Mohan Chintakuntla Date: Tue, 8 Apr 2014 18:51:24 +0530 Subject: arm64, thunder: Add initial dts for Cavium Thunder SoC Add initial device tree nodes for Cavium Thunder SoCs with support of 48 cores and gicv3. The dtsi file requires further changes, esp. for pci, gicv3-its and smmu. This changes will be added later together with the device drivers.
