[Qemu-devel] [PATCH] tests: request access to locality 0 before sending


From: Stefan Berger
Subject: [Qemu-devel] [PATCH] tests: request access to locality 0 before sending command
Date: Mon, 16 Apr 2018 13:48:17 -0400

Recent changes to the CRB code now require that access to locality 0
be requested before the locality can be used for sending a command.
This patch adds the request to access the locality.
