* Copyright (C) 1996-2000 Russell King
*
* Modifications:
* 16-Sep-1996 RMK Inlined the inx/outx functions & optimised for both
* constant addresses and variable addresses.
* 04-Dec-1997 RMK Moved a lot of this stuff to the new architecture
* specific IO header files.
* 27-Mar-1999 PJB Second parameter of memcpy_toio is const..
* 04-Apr-1999 PJB Added check_signature.
* 12-Dec-1999 RMK More cleanups
* 18-Jun-2000 RMK Removed virt_to_* and friends definitions
