e66d741467 target/tricore/helper: Use correct string format in cpu_tlb_fill()
'address' got converted from target_ulong to vaddr in commit
68d6eee73c ("target/tricore: Convert to CPUClass::tlb_fill").
Use the corresponding format string to avoid casting.

348802b526 target: Replace CPU_GET_CLASS(cpu -> obj) in cpu_reset_hold() handler
Since CPU() macro is a simple cast, the following are equivalent:

  Object *obj;
  CPUState *cs = CPU(obj)

In order to ease static analysis when running
scripts/coccinelle/cpu_env.cocci from the previous commit,
replace:

 - CPU_GET_CLASS(cpu);
 + CPU_GET_CLASS(obj);

Most code use the 'cs' variable name for CPUState handle.
Replace few 's' -> 'cs' to unify cpu_reset_hold() style.

No logical change in this patch.

d5be19f514 cpu: Call object_class_dynamic_cast() once in cpu_class_by_name()
For all targets, the CPU class returned from CPUClass::class_by_name()
and object_class_dynamic_cast(oc, CPU_RESOLVING_TYPE) need to be
compatible. Lets apply the check in cpu_class_by_name() for once,
instead of having the check in CPUClass::class_by_name() for individual
target.

9348028e7e target: Move ArchCPUClass definition to 'cpu.h'
The OBJECT_DECLARE_CPU_TYPE() macro forward-declares each
ArchCPUClass type. These forward declarations are sufficient
for code in hw/ to use the QOM definitions. No need to expose
these structure definitions. Keep each local to their target/
by moving them to the corresponding "cpu.h" header.

mention the spacing requirement for QOM"):

  The first declaration of a storage or class structure should
  always be the parent and leave a visual space between that
  declaration and the new code. It is also useful to separate
  backing for properties (options driven by the user) and internal
  state to make navigation easier.

PSW.RM as well.

when we write the PSW using psw_write() we update the rounding modes in
env->fp_status for softfloat. The order of bits used by TriCore is not
the one used by softfloat.

8c0e8ed327 target/tricore: Rename tricore_feature
this name is used by capstone and will lead to a build failure of QEMU,
when capstone is enabled. So we rename it to tricore_has_feature(), to
match has_feature() in translate.c.

a9c37abdff target/tricore: Fix ICR.IE offset in RESTORE insn
from ISA v1.6.1 onwards the bit position of ICR.IE changed.
ctx->icr_ie_offset contains the correct value for the ISA version used
by the vCPU. We also need to exit this tb here, as we might have enabled
interrupts.

19a18edd88 target/tricore: Honour privilege changes on PSW write
the CPU can change the privilege level by writing the corresponding bits
in PSW. If this happens all instructions after this 'mtcr' in the TB are
translated with the wrong privilege level. So we have to exit to the
cpu_loop() and start translating again with the new privilege level.
