7
INSN: instruction set.
8
      OK => all instructions are emulated
9
      KO => some insns are missing or some should be removed
10
      ?  => unchecked
11
SPR:  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
15
MSR:  MSR bits definitions
16
      OK => all MSR bits properly defined
17
      KO => MSR definition is incorrect
18
      ?  => unchecked
19
IRQ:  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
23
MMU:  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
27
EXCP: 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
