While OpenRISC has been around a decade longer than RISC-V and its original support in the Linux kernel dates back to the v3.1 days, on the hardware side OpenRISC hasn't enjoyed nearly as much success as RISC-V and its kernel support not advancing nearly as rapidly. Now with Linux 6.0, OpenRISC is finally exposing PCI bus support...
