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:

Stafford Horne (5):
openrisc/ompic: Add OpenRISC Multicore PIC (OMPIC)
target/openrisc: Make coreid and numcores configurable in state
openrisc/cputimer: Perparation for Multicore
openrisc: Initial SMP support
openrisc: Only kick cpu on timeout, not on update
