CPU Trap Instructions
---------------------
Following instruction will be implemented but only as dummy ones as we are not
implementing privileged instructions. They will all result to exception and core
execution stop.

* [ ] BREAK
* [ ] TEQ
* [ ] TEQI
* [ ] TGE
* [ ] TGEI
* [ ] TGEIU
* [ ] TGEU

* [ ] TLTI
* [ ] TLTIU
* [ ] TLTU
* [ ] TNE
* [ ] TNEI
* SYSCALL won't be implemented at all

Obsolete CPU branch instructions
--------------------------------
None of these instructions will be implemented as they are marked as obsolete and
they shouldn't be used by compiler and the same way by programmers.

FPU Instructions
----------------
No FPU instruction will be implemented as no FPU is planned to be implemented.

Coprocessor Instructions
------------------------
None of these will be implemented as coprocessor 2 won't be implemented.

Privileged instructions
-----------------------
None of these will be implemented as privileged state won't be implemented.

EJTAG Instructions
------------------
No instruction will be implemented as no ejtag support.
