No. Of course this works, but I don't think that it is reasonable
to include qemu-common.h in every *.h file. There are already too
many of them.
target-bfin/cpu.h should start like all other cpu.h files with
these include statements:
sorry, but that's fragile junk. if a header file uses defines from
another
header file, it should be including it.

There are different ways how things can be done.
Normally, I agree with you that each header file should be complete,
but that's not the QEMU style.
In your special case, it's more important to keep all */cpu.h similar.
qemu/target-bfin/cpu.h is still not part of the official QEMU code,
so it can be fixed before it is committed.
Cheers,

IMHO it would be also a clean solution if the */cpu.h no longer include
config.h and qemu-common.h when those files are included in cpu-def.h.
For that solution, your patch could be a starting point, but it needs
more cleanup: include statements which are part of qemu-common.h
need no duplication in cpu-def.h.
