From 796c2b35a4105aa02c6a7af6de659086363d47f7 Mon Sep 17 00:00:00 2001 From: Liviu Dudau Date: Tue, 10 Mar 2015 15:31:37 +0000 Subject: [PATCH] arm64: Add DT support for Juno r1 board. This board is based on Juno r0 with updated Cortex A5x revisions and board errata fixes. It also contains coherent ThinLinks ports on the expansion slot that allow for an AXI master on the daughter card to participate in a coherency domain. Support for SoC PCIe host bridge will be added as a separate series.
