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

From: Stafford Horne
Date: Sun Jul 24 2022 - 22:08:12 EST


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
