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 names for the DSP/IVA2 powerdomains are confusing.

+ * Most OMAP chips have an on-board DSP.
+ *
+ * On the 2420, this is a 'C55 DSP called, simply, the DSP. Its
+ * powerdomain is called the "DSP power domain." On the 2430, the
+ * on-board DSP is a 'C64 DSP, now called (along with its hardware
+ * accelerators) the IVA2 or IVA2.1. Its powerdomain is still called
+ * the "DSP power domain." On the 3430, the DSP is a 'C64 DSP like the
+ * 2430, also known as the IVA2; but its powerdomain is now called the
+ * "IVA2 power domain."
+ *
+ * The 2420 also has something called the IVA, which is a separate ARM
+ * core, and has nothing to do with the DSP/IVA2.
+ *
+ * Ideally the DSP/IVA2 could just be the same powerdomain, but the PRCM
+ * address offset is different between the C55 and C64 DSPs.
