Subject: [PATCH 2/2] arm: zynq: Enable arm_global_timer
Date: Thu, 12 Sep 2013 09:50:40 -0700 [thread overview]
Message-ID: <1379004640-15117-3-git-send-email-soren.brinkmann@xilinx.com> (raw)
In-Reply-To: <1379004640-15117-1-git-send-email-soren.brinkmann@xilinx.com>
Zynq is based on an ARM Cortex-A9 MPCore, which features the
arm_global_timer in its SCU. Therefore enable the timer for Zynq.
