Please read the comments in the list archive that other recently
introduced targets such as moxie and openrisc got.

For instance, I pointed out that new targets don't need a qom-cpu.h file
- you can just place everything into cpu.h if you do a sane grouping.

There was a discussion about CPU VMState and the plan to handle it
differently for new targets - moxie still used the old way, openrisc is
broken, and we don't have patches for a new VMSTATE_CPU() macro yet that
alpha, openrisc and new targets were envisioned to use. Either way
machine.c is a bad name and should rather be cpu-vmstate.c (if you can't
just place it into cpu.c - depends on how much state you have).

Without seeing what you have, it's hard to help. Just look at commits
that introduced the existing targets, get target-tilera compiling and
post RFC patches for review then. We're currently in Soft Freeze before
the 1.5 release, so new targets won't get applied immediately anyway.

Regards,
Andreas
