OpenRISC Enables PCI Support With Linux 6.0
The OpenRISC changes were sent in overnight for the Linux 6.0 merge window. Most notable this cycle is PCI support for OpenRISC. But given the limited OpenRISC hardware, this PCI bus support is intended for use with the QEMU virtualization platform.
Following clean-ups through the PCI tree, the OpenRISC pull has all the Kconfig side enablement for allowing PCI support on OpenRISC that can be enjoyed under QEMU.
OpenRISC changes for Linux 6.0 also include adding a new default configuration "defconfig" for use with QEMU. The new OpenRISC virt defconfig was done for easing OpenRISC development under QEMU to help in moving to more efficient toolchain and kernel testing.
See the OpenRISC changes pull request to Linux 6.0 for the few CPU architecture updates this cycle.
