+Subject: [PATCH] Added support for PPC instructions mfatbu, mfatbl.
+
+Signed-off-by: Aneesh Bansal <aneesh.bansal@freescale.com>
+---
+Currently Valgrind 3.7.0 does not have support for PPC instructions mfatbu and mfatbl. When we run a USDPAA application with VALGRIND, the following error is given by valgrind :
+dis_proc_ctl(ppc)(mfspr,SPR)(0x20F)
+disInstr(ppc): unhandled instruction: 0x7C0F82A6
