[[JPAN]] thanks for the detailed comments, I will fix the style problem in the
 next version. I can separate APB timer code into another patch. But I need
a little more clarification for the abstraction you want. The reason why I did
it this way was it is similar to the other arch_setup_xx, e.g. HPET. In
 io_apic.c 
So do you want to abstract all the arch_setup_xxx in the new abstraction layer?
