Dear friends, I am trying to develop a codec driver (rtlinux driver) from scratch. In Viper board (PXA255) physical memory range 0x40000000-0x43FFFFFF is used by the PXA255 peripherals.In that address range 0x40500000-0x405005FC is needed for AC'97 controller registers. Is this memory range is already mapped to virtual address space, else How to map this to virtual address space. When i tried ioremap() it is giving same virtual address with different physical address(i tried ioremap with another driver(same board)with different physical memory address) Or if this driver already available for RTLinux Please sent me.
