PowerPC emulation status.

The goal of this file is to provide a reference status to avoid regressions.

===============================================================================

PowerPC core emulation status

INSN: instruction set.

      OK => all instructions are emulated

      KO => some insns are missing or some should be removed

      ?  => unchecked

SPR:  special purpose registers set

      OK => all SPR registered (but some may be fake)

      KO => some SPR are missing or should be removed

      ?  => uncheked

MSR:  MSR bits definitions

      OK => all MSR bits properly defined

      KO => MSR definition is incorrect

      ?  => unchecked

IRQ:  input signals definitions (mostly interrupts)

      OK => input signals are properly defined

      KO => input signals are not implemented (system emulation does not work)

      ?  => input signals definitions may be incorrect

MMU:  MMU model implementation

      OK => MMU model is implemented and Linux is able to boot

      KO => MMU model not implemented or bugged

      ?  => MMU model not tested

EXCP: exceptions model implementation

      OK => exception model is implemented and Linux is able to boot

      KO => exception model not implemented or known to be buggy

      ?  => exception model may be incorrect or is untested
