Cover letter [OpenRISC] [PATCH 0/5] OpenRISC SMP Support
Hello,
This series adds SMP support for OpenRISC. The platform is based on the work that Stefan Kristiansson did around 2012 implemented in Verilog and run on FPGAs. I have been working to upstream this work, these are my QEMU patches I have been used to help with testing.
I have documented the platform in the OpenRISC 1.2 specification proposal available here:
https://github.com/stffrdhrn/doc/raw/arch-1.2-proposal/openrisc-arch-1.2-rev0.pdf
My latest kernel patches are available here:
