Subject: [PATCH v3 0/3]  OpenRISC support for virt platform with PCI

Hello,

This is a set of kernel patches which I have been using to support the new QEMU
virt platform [1].  The virt platform supports PCI hence I have a patch here to
add PCI support to OpenRISC.

A defconfig is also included which turns on drivers supported devices include
virt network cards and the goldfish RTC.

Changes since v2:
 - This is based on the pci cleanup patches from
   https://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci.git/log/?h=pci/header-cleanup-immutable
   so pci.h is removed.
 - Change comment about parport.h in patch 2/3.
 - Added a patch to define __pci_ioport_map as NULL when when IO ports
   are not supported.
Changes since v1:
 - Remove PIO support as suggest by Arnd

  asm-generic: Support NO_IOPORT_MAP in pci_iomap.h
  openrisc: Add pci bus support
  openrisc: Add virt defconfig
