04a130eaa1 target-unicore32: switch to AREG0 free mode
Add an explicit CPUState parameter instead of relying on AREG0
and switch to AREG0 free mode.

f3ccc32369 unicore32-softmmu: Implement softmmu specific functions
This patch implements softmmu specific functions, include tlb_fill,
switch_mode, do_interrupt and uc32_cpu_handle_mmu_fault.
So the full exception handlers and page table walking could work now.

4f23a1e645 unicore32-softmmu: Add unicore32-softmmu build support
This patch adds unicore32-softmmu build support, include configure,
makefile, arch_init, and all missing functions needed by softmmu.
Although all missing functions are empty, unicore32-softmmu could
be build successfully.
By 20120804: change QEMU_ARCH_UNICORE32 to 0x4000

2b3bc6c0f5 target-unicore32: Relicense to GPLv2+
Adopt the license text suggested by Guan Xue-tao (with a minor
simplification) for all target-unicore/ files except helper.c.

To helper.c Anthony Liguori contributed a qemu_malloc() -> g_malloc()
conversion, still pending IBM relicensing approval, so that remains
GPLv2 for now.

By relicensing all possible parts now, we avoid having to formally
relicense new, e.g., QOM code.

eb23b556aa target-unicore32: Don't overuse CPUState
Scripted conversion:
  sed -i "s/CPUState/CPUUniCore32State/g" target-unicore32/*.[hc]
  sed -i "s/#define CPUUniCore32State/#define CPUState/" target-unicore32/cpu.h

3e4571724f exec.h cleanup
Move softmmu_exec.h include directives from target-*/exec.h to
target-*/op_helper.c. Move also various other stuff only used in
op_helper.c there.

Define global env in dyngen-exec.h.

For i386, move wrappers for segment and FPU helpers from user-exec.c
to op_helper.c. Implement raise_exception_err_env() to handle dynamic
CPUState. Move the function declarations to cpu.h since they can be
used outside of op_helper.c context.

LM32, s390x, UniCore32: remove unused cpu_halted(), regs_to_env() and
env_to_regs().

ARM: make raise_exception() static.

Convert
#include "exec.h"
to
#include "cpu.h"
#include "dyngen-exec.h"
and remove now unused target-*/exec.h.

Make cpu_loop_exit() take a parameter for CPUState instead of relying
on global env.
