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

PowerPC microcontrollers emulation status

Implemementation should be sufficient to boot Linux:
(there seem to be problems with uboot freezing at some point)
- PowerPC 405CR
- PowerPC 405EP

TODO:
- PowerPC 401 microcontrollers emulation
- PowerPC 403 microcontrollers emulation
- more PowerPC 405 microcontrollers emulation
- Fixes / more features for implemented PowerPC 405 microcontrollers emulation
- PowerPC 440 microcontrollers emulation
- e200 microcontrollers emulation
- e300 microcontrollers emulation
- e500 microcontrollers emulation
- e600 microcontrollers emulation

PowerPC based platforms emulation status

* PREP platform (RS/6000 7043...) - TO BE CHECKED (broken)
- Gentoo Linux live CDROM 1.4
- Debian Linux 3.0
- Mandrake Linux 9

* heathrow PowerMac platform (beige PowerMac) - TO BE CHECKED (broken)
- Gentoo Linux live CDROM 1.4
- Debian Linux 3.0
- Mandrake Linux 9

* mac99 platform (white and blue PowerMac, ...)
- Gentoo Linux live CDROM 1.4 - boots, compiles linux kernel
- Debian Linux woody - boots from CDROM and HDD
- Mandrake Linux 9 - boots from CDROM, freezes during install
- Knoppix 2003-07-13_4 boots from CDROM, pb with X configuration
  distribution bug: X runs with a properly hand-coded configuration.
- rock Linux 2.0 runs from CDROM

* Linux 2.6 support seems deadly broken (used to boot...).

* PowerPC 405EP reference boards:
- can boot Linux 2.4 & 2.6.
  Need to provide a flash image ready to boot for reproductible tests.

TODO:
- URGENT: fix PreP and heathrow platforms
- PowerPC 64 reference platform
- MCA based RS/6000 emulation
- CHRP emulation (not PowerMac)
- PPAR emulation
- ePPAR emulation
- misc PowerPC reference boards emulation
