Add #ifdef to avoid compiling not relevant resources:
- MMU related stuff for user-mode only targets
- PowerPC 64 only resources for PowerPC 32 targets
- embedded PowerPC extensions for non-ppcemb targets.

memory segments.

Improve TLB & SLB search debug traces.
Temporary hack to make PowerPC 970 boot from ROM instead of RAM.

call the helpers directly from the micro-ops.
Avoid duplicated code for tlbsx. implementation.

- New mtmsr/mtmsrd form that just update RI and EE bits
- New hrfid, lq and stq instructions
- Add support for supervisor and hypervisor modes process priority update
- Code provision for hypervisor SPR accesses
* Actually implement the wait instruction

Share most code with the time-base management routines.
Remove time-base write routines from user-mode emulation environments.

* don't use exception vectors as the exception number.
Use vectors numbers as defined in the PowerPC embedded specification instead
and extend this model to cover all emulated PowerPC variants exceptions.
* add some missing exceptions definitions, from PowerPC 2.04 specification
and actual PowerPC implementations.
* add code provision for hypervisor exceptions handling.
* define exception vectors and prefix in CPUPPCState to emulate BookE exception
vectors without any hacks.
* define per CPU model valid exception vectors.
* handle all known exceptions in user-mode only emulations.
* fix hardware interrupts priorities in most cases.
* change RET_EXCP macros name into GEN_EXCP as they don't return.
* do not stop translation on most instructions that are not defined as
context-synchronizing in PowerPC specification.
* fix PowerPC 64 jump targets and link register update when in 32 bits mode.
* Fix PowerPC 464 and 464F 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.

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.

As a side effect, avoid potential bits shadowing in TB flags on 64 bits BookE.

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.

Move cpu_ppc_init, cpu_ppc_close, cpu_ppc_reset and ppc_tlb_invalidate
into helper.c as they are to be called from outside of the translated code.
git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@2682 c046a42c-6fe2-441c-8c8c-71466251a162
move all PowerPC specific code into target-ppc/helper.c to avoid polluting
the common code in cpu-exec.c. This makes implementation of new features
(ie embedded PowerPC timers, critical interrupts, ...) easier.
This also avoid hardcoding the IRQ callback in the OpenPIC controller,
making it more easily reusable and allowing cascading.
