Once upon the time when QEMU hacking was fun
there was a brave knight who wanted to have
a driver for a special intel nic.
So he started by cloning ne2000.c which also
meant that the new born eepro100.c was
immediately three years old.
Other knights who also wanted to have fun and
take their part in the battle thought that it
would be a good idea to remove stupid code
which says "missing nic load, missing nic save".
They saved everything they saw, man and women,
ne2000 code and runtime address offsets, and
put all saved elements in a prison called
vm data.
When the first knight came back and noticed
the unhappy prisoners, he wanted to set them
free. But the keepers of the keys told him
that they would have to stay there forever
for compatibility reasons.
So our brave knight now takes a new effort
to save the souls of the poor prisoners by
removing their names.
Their bodies will have to rot in the dungeons
of compatibility forever, watched by the
keepers of the keys.

- keep the coordinates even when no button is pressed, on real tablet

and drivers expect this,
- map left button to pressure according to what the Haiku driver wants,
- map the right button to the pen button,
- map the middle button to the eraser,

Like qdev_init(), but terminate program via hw_error() instead of
returning an error value.
Use it instead of qdev_init() where terminating the program on failure
is okay, either because it's during machine construction, or because
we know that failure can't happen.
Because relying in the latter is somewhat unclean, and the former is
not always obvious, it would be nice to go back to qdev_init() in the
not-so-obvious cases, only with proper error handling. I'm leaving

This patch adds infrastructure to maintain memory regions which must be
restored on reset. That includes roms (vga bios and option roms on pc),
but is also used when loading linux kernels directly. Features:
- loading files is supported.
- passing blobs is supported.
- target address range is supported (for optionrom area).
- fixed target memory address is supported (linux kernel).
New in v2:
- writes to ROM are done only at initial boot.
- also handle aout and uimage loaders.
- drop unused fread_targphys() function.
The final memory layout is created once all memory regions are
registered. The option roms get addresses assigned and the
registered regions are checked against overlaps. Finally all data
is copyed to the guest memory.
Advantages:
(1) Filling memory on initial boot and on reset takes the same
code path, making reset more robust.
(2) The need to keep track of the option rom load address is gone.
(3) Due to (2) option roms can be loaded outside pc_init(). This
allows to move the pxe rom loading into the nic drivers for
example.
Additional bonus: There is a 'info roms' monitor command now.
The patch also switches over pc.c and removes the
option_rom_setup_reset() and load_option_rom() functions.

This adds a exit callback for device destruction to DeviceInfo, so
we can hook cleanups into qdev device destruction.
Followup patches will put that into use.

Two bug fixes:
* When freeing a device we unregister even stuff we didn't register in
the first place because the ->init() callback failed.
* When freeing a device with child busses attached, we fail to zap the
child bus (and the devices attached to it).
