From: Rashmica Gupta Date: Wed, 23 Dec 2015 05:49:50 +0000 (+1100) Subject: selftests/powerpc: Make reg.h common to all powerpc selftests X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=2d59b3b25659463a24f05df367574d90b3cd7145;p=deliverable%2Flinux.git selftests/powerpc: Make reg.h common to all powerpc selftests Currently there is a reg.h in pmu/ebb that has defines that are useful in other powerpc selftests so move this up into selftests/powerpc folder. Also include in utils.h - as this is often used in self tests. Add in some other useful register defines.
