Subject: [kvm-unit-tests PATCH v2 04/14] powerpc/ppc64: start skeleton framework
Date: Mon, 8 Feb 2016 19:53:04 +0100 [thread overview]
Message-ID: <1454957594-30601-5-git-send-email-drjones@redhat.com> (raw)
In-Reply-To: <1454957594-30601-1-git-send-email-drjones@redhat.com>
Use the arm/arm64 framework as a template to start a skeleton
for powerpc/ppc64. Copy the arm makefiles and linker script
verbatim. We'll modify them for powerpc with the next patch,
making it clear what needs to be changed.
