The following series includes emulation of the platform-specific MIPS extension
for Cavium Octeon CPUS:
- basic Octeon vCPU model
- custom instruction decoder for Octeon
- implementation of arithmetic and logic instructions

Pavel Dovgalyuk (3):
      target/mips: introduce generic Cavium Octeon CPU model
      target/mips: implement Octeon-specific BBIT instructions
      target/mips: implement Octeon-specific arithmetic instructions
