lib: use generic pci_iomap on all architectures Many architectures don't want to pull in iomap.c, so they ended up duplicating pci_iomap from that file. That function isn't trivial, and we are going to modify it https://lkml.org/lkml/2011/11/14/183 so the duplication hurts. This reduces the scope of the problem significantly, by moving pci_iomap to a separate file and referencing that from all architectures. * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost: alpha: drop pci_iomap/pci_iounmap from pci-noop.c mn10300: switch to GENERIC_PCI_IOMAP mn10300: add missing __iomap markers frv: switch to GENERIC_PCI_IOMAP tile: switch to GENERIC_PCI_IOMAP tile: don't panic on iomap sparc: switch to GENERIC_PCI_IOMAP sh: switch to GENERIC_PCI_IOMAP powerpc: switch to GENERIC_PCI_IOMAP parisc: switch to GENERIC_PCI_IOMAP mips: switch to GENERIC_PCI_IOMAP microblaze: switch to GENERIC_PCI_IOMAP arm: switch to GENERIC_PCI_IOMAP alpha: switch to GENERIC_PCI_IOMAP lib: add GENERIC_PCI_IOMAP lib: move GENERIC_IOMAP to lib/Kconfig Fix up trivial conflicts due to changes nearby in arch/{m68k,score}/Kconfig
2011-11-28lib: add GENERIC_PCI_IOMAPMichael S. Tsirkin1-2/+2
Many architectures want a generic pci_iomap but not the rest of iomap.c. Split that to a separate .c file and add a new config symbol. select automatically by GENERIC_IOMAP. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>

2011-07-22iomap: make IOPORT/PCI mapping functions conditionalJonas Bonn1-0/+2
Use the CONFIG_HAS_IOPORT and CONFIG_PCI options to decide whether or not functions for mapping these areas are provided. Signed-off-by: Jonas Bonn <jonas@southpole.se> Acked-by: Arnd Bergmann <arnd@arndb.de>
2011-07-22asm-generic: add MMU variants of io.h functionsJonas Bonn1-1/+6
Some of the implementations, in particular the ioremap variants, in asm-generic/io.h are for systems without an MMU. In order to be able to use the generic header file for systems with an MMU, this patch wraps these implementations in checks for CONFIG_MMU. Tested on OpenRISC.

2011-03-17asm-generic: fix inX/outX functions for architectures that have PCIGuanXuetao1-14/+19
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.

2011-01-10asm-generic/io.h: add reads[bwl]/writes[bwl] helpersMike Frysinger1-0/+30
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 <arnd@arndb.de> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-10-18asm-generic/io.h: allow people to override individual funcsMike Frysinger1-0/+26
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 <vapier@gentoo.org> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2010-08-10asm-generic/io.h: add big endian versions of io{read,write}{16,32}Mike Frysinger1-0/+4
The asm-generic/iomap.h provides these functions already, but the non-generic fallback defines do not.

2009-06-11asm-generic: add generic atomic.h and io.hArnd Bergmann1-0/+300
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 <arnd@arndb.de>
