+This BSP is designed to operate on the PPC simulator provided by qemu.
+We are using the Courverture Project's qemu source tree.
+
+Couverture Project to add tracing/coverage to qemu
+  http://libre.adacore.com/libre/tools/coverage/
+
+Their source repository
+  http://forge.open-do.org/scm/?group_id=8
+
+That has instructions on checking it out.
+
+If you check it out into ${BASE} directory, then the
+directory with their modified qemu is:
+
+  ${BASE}/couverture/trunk/couverture/tools/qemu-r6588
+
+My BASE is /home/joel/qemu-coverage.  I configured like this
+from within the qemu source tree.
+
+  ./configure --prefix=/home/joel/qemu-coverage/install
+  make
+  make install
+
+This gives all simulated targets supported.  
+
+See the Makefile for more details.
+
