[Qemu-devel] [PATCH v2 0/5] OpenRISC SMP Support

[Stafford Horne <shorne@gmail.com>]

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:
