b41f7df018 CRIS updates: 
* Support both the I and D MMUs and improve the accuracy of the MMU model.
* Handle the automatic user/kernel stack pointer switching when leaving or entering user mode.
* Move the CCS evaluation into helper funcs.
* Make sure user-mode cannot change flags only writeable in kernel mode.
* More conversion of the translator into TCG.
* Handle exceptions while in a delayslot.

3157a0a93b More TCG conversions for CRIS. 
* Bit swap insn (bitwise not, endian swap and bit reverse).
* Muls and mulu.
* Extended arithmetics.
* Parts of the condition code handling.
* Use tcg_const_tl.

bbaf29c769 * target-cris/op.c: Make sure the bit-test insn only updates the XNZ flags. 
* target-cris/helper.c: Update ERP for user-mode simulation aswell.
* hw/etraxfs_timer.c: Support multiple timers.
* hw/etraxfs_ser.c: Multiple ports, the data just goes to stdout.

4f400ab520 Cut the translation block after translating a break insn. This avoids an issue where QEMU finds an illegal CRIS insn while the guest is returning through a signal return trampoline.

6ebbf39000 Replace is_user variable with mmu_idx in softmmu core, 
allowing support of more than 2 mmu access modes.
Add backward compatibility is_user variable in targets code when needed.
Implement per target cpu_mmu_index function, avoiding duplicated code
  and #ifdef TARGET_xxx in softmmu core functions.
Implement per target mmu modes definitions. As an example, add PowerPC
  hypervisor mode definition and Alpha executive and kernel modes definitions.
Optimize PowerPC case, precomputing mmu_idx when MSR register changes
  and using the same definition in code translation code.
