asm-generic: fix inX/outX functions for architectures that have PCI

2011-03-17T01:19:03Z

The definitions for the PC-style PIO functions in asm-generic/io.h were meant as dummies so you could compile code on architectures without ISA and PCI buses. However, unicore32 actually wants to use them with a real PCI bus, so they need to be defined to actually address the register window holding the I/O ports. Signed-off-by: Arnd Bergmann

asm-generic/io.h: add reads[bwl]/writes[bwl] helpers

2011-01-10T12:18:03Z

A bunch of arches define reads[bwl]/writes[bwl] helpers for accessing memory mapped registers. Since the Blackfin ones aren't specific to Blackfin code, move them to the common asm-generic/io.h for people. Acked-by: Arnd Bergmann Signed-off-by: Mike Frysinger

asm-generic/io.h: allow people to override individual funcs

2010-10-18T07:20:46Z

For the Blackfin port, we can use much of the asm-generic/io.h header, but we still need to declare some of our own versions of functions. Like the __raw_read* and in/out "string" helpers. So let people do this easily for many of these funcs. Signed-off-by: Mike Frysinger Signed-off-by: Arnd Bergmann

asm-generic/io.h: add big endian versions of io{read,write}{16,32}

2010-08-10T03:45:04Z

The asm-generic/iomap.h provides these functions already, but the non-generic fallback defines do not. Signed-off-by: Mike Frysinger Cc: Arnd Bergmann Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

asm-generic: add generic atomic.h and io.h

2009-06-11T19:02:49Z

atomic.h and io.h are based on the mn10300 architecture, which is already pretty generic and can be used by other architectures that do not have hardware support for atomic operations or out-of-order I/O access. Signed-off-by: Arnd Bergmann
