j_mayer a750fc0b91 Great rework and cleanups to ease PowerPC implementations definitions. 
* 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.

j_mayer 2662a059aa More PowerPC definitions, from POWER 2.04 specifications and misc sources. 
Check that at least instructions set and SPRs are correct for
 PowerPC 401, 403, 405 and 440 cores.
Implement PowerPC 401 MMU model (real-mode only).
Improve INSNs and SPRs dump to ease parse with standard shell tools.
Add more precise status for most PowerPC cores families.

j_mayer d9d7210c7d Fix PowerPC 32 emulation on 64 bits hosts: 
we can use 64 bits registers but not pretend page is 1kB long
As it seems most Linux programs assume page-size is 4kB, never allow
1kB pages for user-mode only emulation.
