register reads...

Please. This has had us stopped dead since it was merged.
For a quick fix you can comment out leon3_cpu_counter_initialize() in
bsp_start().
Ok, then that's the temporary fix.
As far as I am concerned it can be committed since it fixes a breakage. When
Sebastian has a working solution, we can test that.
I would have helped if someone tried to answer my questions. I will send a
patch on Monday that hopefully satisfies everyone.
I will focus on answering your email instead. It might be hard to satisfy
everyone though, I'm not convinced what to do in this case my self at the
moment.
