Hi
Some more doubts about the same thing.
As I am aware, the MPC8260 does not have a separate I/O address space. So,
with reference to my earlier mail, when do we need to use ioremap() and when
do we need to use request_mem_region()? Or do we need to use both in a
particular sequence?
Also, if I just do an ioremap(), can I directly access those remapped
addresses with inb()/outb() or writeb()/readb()? Or is something more to be
done prior to accessing it?
