   5PowerPC core emulation status
   6
   7INSN: instruction set.
   8      OK => all instructions are emulated
   9      KO => some insns are missing or some should be removed
  10      ?  => unchecked
  11SPR:  special purpose registers set
  12      OK => all SPR registered (but some may be fake)
  13      KO => some SPR are missing or should be removed
  14      ?  => unchecked
  15MSR:  MSR bits definitions
  16      OK => all MSR bits properly defined
  17      KO => MSR definition is incorrect
  18      ?  => unchecked
  19IRQ:  input signals definitions (mostly interrupts)
  20      OK => input signals are properly defined
  21      KO => input signals are not implemented (system emulation does not work)
  22      ?  => input signals definitions may be incorrect
  23MMU:  MMU model implementation
  24      OK => MMU model is implemented and Linux is able to boot
  25      KO => MMU model not implemented or bugged
  26      ?  => MMU model not tested
  27EXCP: exceptions model implementation
  28      OK => exception model is implemented and Linux is able to boot
  29      KO => exception model not implemented or known to be buggy
  30      ?  => exception model may be incorrect or is untested
