Alexey Kardashevskiy 81d2fb4dfd target-ppc: remove powerpc 970gx
The 970GX definition was added in 2007 and it made sense then but this
version has never been released to the markets and it does not exist in
the real world so there is no point in emulating it.

This removes 970GX.

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
? => unchecked
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
