* cleanup cpu.h, removing definitions used only in translate.c/translate_init.c * add new flags to define instructions sets more precisely * various changes in MMU models definitions * add definitions for PowerPC 440/460 support (insns and SPRs). * add definitions for PowerPC 401/403 and 620 input pins model * Fix definitions for most PowerPC 401, 403, 405, 440, 601, 602, 603 and 7x0 * Preliminary support for PowerPC 74xx (aka G4) without altivec. * Code provision for other PowerPC support (7x5, 970, ...). * New SPR and PVR defined, from PowerPC 2.04 specification and other sources * Misc code bugs, error messages and styles fixes. * Update status files for PowerPC cores support. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@3244 c046a42c-6fe2-441c-8c8c-71466251a162

===============================================================================
|
|
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
