Hi Some more doubts about the same thing.
As I am aware, the MPC8260 does not have a separate I/O address space. > Yes,The MPC8260 I/O address space is mapped into > the Processors address space itself i,e the 256 Kb > Internal memory which can be located anywhere in the > 4 GB adress space using the IMMR register 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? > For the MPC8260 you can access the I/O region > directly without an need for mapping.U can access > it thru the IMMR base address value.And specific > registers can be accessed by adding the register > offset to this value 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? > u dont have to do an ioremap Regards Vijay Padiyar http://www.vijaypadiyar.eu.tf __________________________________ Do you Yahoo!? Yahoo!
