Define and initialize the 16 MXU registers - 15 general computational
register, and 1 control register). There is also a zero register, but
it does not have any corresponding variable.

Define a bit for MXU in insn_flags. This is the first non-MIPS
(third party) ASE supported in QEMU for MIPS, so it is placed in
the section "bits 56-63: vendor-specific ASEs".

Amend MXU instruction opcodes. Pool04 is actually only instruction
OPC_MXU_S16MAD. Two cases within S16MAD are recognized by 1-bit
subfield 'aptn1'.

Provide the placeholder and add the invocation logic for MXU
decoding engine.

Is the best way to implement this to include processing of MUL, CLZ,
CLO, SDDP instructions into decode_opc_mxu as their encodings aren't
overlaid by MXU instructions
considering MIPS SPECIAL2 instruction pool and MXU Instruction Set?

The problem is that we don't have the documentation for Ingenic's base
instruction set. My understanding is that Craig established necessity of
including non-MXU MUL into decode_opc_mxu() by experimentation,
or by looking at Ingenic's toolchain source code.
Note that CLZ, CLO, SDBBP are moved from SPECIAL2 to another
place in opcode space in MIPS R6.
Craig, can you offer any insight on CLZ, CLO, SDBBP in Ingenic's base
instruction set? They are in SPECIAL2 opcode space for MIPS pre-R6.
Worse come to worst, I recommend adding "TODO" comment to an
appropriate place in decode_opc_mxu(), and go forward without handling
CLZ, CLO, SDBBP - given that all changes in this series are just the first
phase of implementing MXU support - they won't affect any production
code at this moment.
I appreciate your review,
Aleksandar

I think this comment should be added to the decode_opc_mxu(), within patch 11:
/*
* TODO: Investigate necessity of including handling of
* CLZ, CLO, SDBB in this function, as they belong to
* SPECIAL2 opcode space for regular pre-R6 MIPS ISAs.
*/
Thanks,
Aleksandar

In that case, I guess this should be OK for now, as MXU support is
initiated by Craig and this will be
an easy add-on when he provide necessary information.

Add MXU decoding engine: add handlers for all instruction pools,
and main decode handler. The handlers, for now, for the purpose
of this patch, contain only sceleton in the form of a single
switch statement.

Add support for emulating the S32I2M and S32M2I MXU instructions.
This commit also contains utility functions for reading/writing
to MXU registers. This is required for overall MXU instruction
support.
