This is an unrelated change which shouldn't be in this patch. I squashed
this series in the original commit adding udoo support anyway. so it
doesn't matter in this case.
BTW what does this EPIT initialization do and what do you need it for?
It's quite unusual to initialize the EPIT since it's not used by
barebox.
