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.
