88552b16f2 hw/misc/vmcoreinfo: Add comment about reset handler
The VM coreinfo device does not sit on a bus, so it won't be
reset automatically. This is why it calls qemu_register_reset().

Add a comment about it, so we don't convert its reset handler
to a DeviceReset method.

d645427057 Include migration/vmstate.h less
In my "build everything" tree, changing migration/vmstate.h triggers a
recompile of some 2700 out of 6600 objects (not counting tests and
objects that don't depend on qemu/osdep.h).

hw/hw.h supposedly includes it for convenience.  Several other headers
include it just to get VMStateDescription.  The previous commit made
that unnecessary.

Include migration/vmstate.h only where it's still needed.  Touching it
now recompiles only some 1600 objects.

71e8a91585 Include sysemu/reset.h a lot less
In my "build everything" tree, changing sysemu/reset.h triggers a
recompile of some 2600 out of 6600 objects (not counting tests and
objects that don't depend on qemu/osdep.h).

The main culprit is hw/hw.h, which supposedly includes it for
convenience.

Include sysemu/reset.h only where it's needed.  Touching it now
recompiles less than 200 objects.

5be5df720e fw_cfg: import & use linux/qemu_fw_cfg.h
Use kernel common header for fw_cfg.

(unfortunately, optionrom.h must have its own define, since it's
actually an assembler header)
