Hi,

Weekends tend to be slow around here.

The BSP can be run, but there are performance problems with it,
indicating the cache configuration is wrong.

So far the RPi2 only works on a single core. Getting it to work well
on all 4-cores is the goal. Then you can consider stretch goals that
could be optional, for example if there are peripherals available on
rpi2 that aren't on rpi, or to do something else with SMP-support.

This is a suitable project.

Estimating time is hard. I'd recommend working out what needs to be
done first, and we can try to help you decide if you proposed too much
or too little. It would be good for you to study some of the other SMP
targets, especially the ARM ones, and to see what SMP-support is
required at the BSP level. I think some of this info is available in
the documentation, but you might have to hunt for the info because SMP
is still quite new in RTEMS.
