Hi wolfgang:
I think vipin here is trying to provide a generic timer support for ARMV7
architecture,
which contains private(local) and global timer. It's general a good thing
which means we can maximize the code usage..
Actually I was planing to test the code, but haven't find the time yet ;-)

Hi vipin:
why you only support local timer(private)? shouldn't it different to
support global timer too?
