   5 PowerPC core emulation status
   6
   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       ?  => uncheked
  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

 519 - Gentoo Linux live CDROM 1.4 - boots, compiles linux kernel
 520 - Debian Linux woody - boots from CDROM and HDD
 521 - Mandrake Linux 9 - boots from CDROM, freezes during install
 522 - Knoppix 2003-07-13_4 boots from CDROM, pb with X configuration
 523   distribution bug: X runs with a properly hand-coded configuration.
 524 - rock Linux 2.0 runs from CDROM
 525
 526 * Linux 2.6 support seems deadly broken (used to boot...).
 527
 528 * PowerPC 405EP reference boards:
 529 - can boot Linux 2.4 & 2.6.
 530   Need to provide a flash image ready to boot for reproductible tests.
