Reviewed-by: James Morse <james.morse at arm.com> A quick test of this took longer than expected (writing to a slow usb device), I suspect it is save/restoring the whole crash region (which I don't think is a problem). If someone turns out to use this combination of features I will look at improving this, (almost certainly requires core-code changes). Thanks, James
