PCI: collapse pcibios_resource_to_bus

2012-02-24T03:19:04+00:00

Everybody uses the generic pcibios_resource_to_bus() supplied by the core
now, so remove the ARCH_HAS_GENERIC_PCI_OFFSETS used during conversion.

sh/PCI: get rid of device resource fixups

2012-02-24T03:19:03+00:00

Tell the PCI core about host bridge address translation so it can take
care of bus-to-resource conversion for us.

PCI: Make the struct pci_dev * argument of pci_fixup_irqs const.

2011-07-22T15:26:06+00:00

Aside of the usual motivation for constification,  this function has a
history of being abused a hook for interrupt and other fixups so I turned
this function const ages ago in the MIPS code but it should be done
treewide.

Due to function pointer passing in varous places a few other functions
had to be constified as well.

sh: pci: Use a generic raw spinlock for PCI config access locking.

2010-09-20T09:56:13+00:00

This copies the pci_config_lock idea from x86 over, allowing us to kill
off a couple of existing private locks. At the same time, these need to
be converted to raw spinlocks for -rt kernels, so we make that change at
the same time. This should make it easier for future parts to get the
locking right instead of inevitable ending up with lock type mismatches.

pci-dma: add linux/pci-dma.h to linux/pci.h

2010-03-12T23:52:42+00:00

All the architectures properly set NEED_DMA_MAP_STATE now so we can safely
add linux/pci-dma.h to linux/pci.h and remove the linux/pci-dma.h
inclusion in arch's asm/pci.h

sh: Fix up early PCI PERR/SERR IRQ handling.

2010-02-03T07:46:20+00:00

This adds support for handling early PERR/SERR triggering in between
controller registration and the initial bus scan. Buggy cards end up
asserting these as soon as the M66EN scan is undertaken, resulting in
an early crash.

sh: Improved multi-resource handling for SH7780 PCI.

2010-02-01T11:01:50+00:00

The SH7780 PCI controller supports 3 different ranges of PCI memory in
addition to its PCI I/O window. In the case of 29-bit mode, only 2 memory
windows are supported, while in 32-bit mode all 3 are visible. This
attempts to make the resource handling completely dynamic and to permit
platforms to map in as many apertures as they can handle.

sh: Hook up ERR/PERR/SERR detection for SH7780 PCI host controllers.

2010-02-01T07:39:46+00:00

These were never handled before, so implement some common infrastructure
to support them, then make use of that in the SH7780-specific code. In
practice there is little here that can not be generalized for SH4 parts,
which will be an incremental change as the 7780/7751 code is gradually
unified.

sh: Handle PCI controller resource conflicts.

2010-02-01T04:11:25+00:00

register_pci_controller() can fail, but presently is a void function.
Change this over to an int so that we can bail early before continuing on
with post-registration initialization (such as throwing the controller in
to 66MHz mode in the case of the SH7780 host controller).
