GPTIMER[0].timer0 (system clock timer) and remove the AMBA scanning. If Sebastian

course, if an IRQ is received inbetween or a wraparound happens the value could
not be trusted, however I believe a loop could be added that compares values
between 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().
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.
