Add the rt linux 4.1.3-rt3 as base
Import the rt linux 4.1.3-rt3 as OPNFV kvm base. It's from git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-rt-devel.git linux-4.1.y-rt and the base is: commit 0917f823c59692d751951bf5ea699a2d1e2f26a2 Author: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Date: Sat Jul 25 12:13:34 2015 +0200 Prepare v4.1.3-rt3 Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> We lose all the git history this way and it's not good. We should apply another opnfv project repo in future. Change-Id: I87543d81c9df70d99c5001fbdf646b202c19f423 Signed-off-by: Yunhong Jiang <yunhong.jiang@intel.com>

+
+ The board also incorporates a power supply and is a Power over Ethernet (PoE) Powered
+ Device (PD).
+
+ Additionally, a Cyclone III FPGA from Altera is integrated on the board. The FPGA is
+ mapped into the 32-bit AVR memory bus. The FPGA offers two DDR2 SDRAM interfaces, which
+ will cover even the most exceptional need of memory bandwidth. Together with the onboard
+ video decoder the board is ready for video processing.

+ * that may have been sbrk'ed. No attempt is made to determine if a
