Subject: [PATCH v2 0/2] 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 v1:

 - Remove PIO support as suggest by Arnd

Stafford Horne (2):
  openrisc: Add pci bus support
  openrisc: Add virt defconfig
