[PATCH 5/5] arm64: Add DT support for Juno r1 board.

Liviu Dudau Liviu.Dudau at arm.com
Wed May 13 10:11:32 PDT 2015


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.
