PowerPC microcontrollers emulation status
498
Implemementation should be sufficient to boot Linux:
499
(there seem to be problems with uboot freezing at some point)
504
- PowerPC 401 microcontrollers emulation
505
- PowerPC 403 microcontrollers emulation
506
- more PowerPC 405 microcontrollers emulation
507
- Fixes / more features for implemented PowerPC 405 microcontrollers emulation
508
- PowerPC 440 microcontrollers emulation
509
- e200 microcontrollers emulation
510
- e300 microcontrollers emulation
511
- e500 microcontrollers emulation
512
- e600 microcontrollers emulation

PowerPC based platforms emulation status
517
* PREP platform (RS/6000 7043...) - TO BE CHECKED (broken)
518
- Gentoo Linux live CDROM 1.4
522
* heathrow PowerMac platform (beige PowerMac) - TO BE CHECKED (broken)
523
- Gentoo Linux live CDROM 1.4
527
* mac99 platform (white and blue PowerMac, ...)
528
- Gentoo Linux live CDROM 1.4 - boots, compiles linux kernel
529
- Debian Linux woody - boots from CDROM and HDD
530
- Mandrake Linux 9 - boots from CDROM, freezes during install
531
- Knoppix 2003-07-13_4 boots from CDROM, pb with X configuration
532
distribution bug: X runs with a properly hand-coded configuration.
533
- rock Linux 2.0 runs from CDROM
535
* Linux 2.6 support seems deadly broken (used to boot...).
537
* PowerPC 405EP reference boards:
538
- can boot Linux 2.4 & 2.6.
539
Need to provide a flash image ready to boot for reproductible tests.
542
- URGENT: fix PreP and heathrow platforms
543
- PowerPC 64 reference platform
544
- MCA based RS/6000 emulation
545
- CHRP emulation (not PowerMac)
548
- misc PowerPC reference boards emulation
