Subject: [PATCH v5 0/4] Cleanups for asm-generic/pci.h

When reviewing the OpenRISC PCI support patch Arnd suggested that
we avoid copying arm64 and riscv asm/pci.h and moving that to be
the new asm-generic/pci.h.

This patch does that by first removing the old pci.h with the definition of
pci_get_legacy_ide_irq completely. We replace it with references to
ATA_PRIMARY_IRQ and ATA_SECONDARY_IRQ macros.

Next, we do further cleanups moving isa_dma_bridge_buggy to be only
x86_32 specific.  This avoids having to have it in dma.h or pci.h headers.

Next, we create the new pci.h definition.

Note, for the series, I am working on these fixups as part of adding PCI to
OpenRISC.  If the series is accepted I would like to merge via the OpenRISC tree
with the OpenRISC PCI support patches to avoid having to coordinate upstream
merges.

Since v4:
 - Move some pci_get_legacy_ide_irq and isa_dma_bridge_buggy cleanups
   into the correct patches.
 - Add csky ARCH_GENERIC_PCI_MMAP_RESOURCE definition patch, suggested by Arnd
Since v3:
 - We now completely remove pci_get_legacy_ide_irq and use libata.h macros.
 - Added a new patch to remove isa_dma_bridge_buggy in architectures
   other than x86_32.
Since v2:
 - Remove pci_get_legacy_ide_irq from m68k.
Since v1:
 - Remove definition of pci_get_legacy_ide_irq on architectures
   not using CONFIG_PNP, which eliminated most.
 - Add ifdef around PCIBIOS_MIN_MEM for consistency.

Stafford Horne (4):
  PCI: Remove pci_get_legacy_ide_irq and asm-generic/pci.h
  PCI: Move isa_dma_bridge_buggy out of dma.h
  csky: PCI: Define ARCH_GENERIC_PCI_MMAP_RESOURCE
  asm-generic: Add new pci.h and use it
