Subject: [PATCH v2 1/1] arm64: dts: NS2 secondary core enablement via PSCI
Date: Wed, 20 Apr 2016 13:40:02 -0400
Message-Id: <1461174002-18178-1-git-send-email-luke.starrett@broadcom.com>
X-Mailer: git-send-email 2.1.0

Declare PSCI-1.0 node and enable CPU_ON method via PSCI.  Spin-table
memreserve has been removed as well as syscon based reset, as PSCI-1.0
expects reset implementation in firmware.
