hw/char/serial currently contains the implementation of both TYPE_SERIAL and
TYPE_SERIAL_MM. According to serial_class_init(), TYPE_SERIAL is an internal
class while TYPE_SERIAL_MM is used by numerous machine types directly. Let's
move the latter into its own module which makes the dependencies more obvious
and the code more tidy.
The includes and the dependencies have been converted mechanically except in the
hw/char directories which were updated manually. The result was compile-tested.
Now, only hw/char makes direct use of TYPE_SERIAL:
# grep -r -e "select SERIAL" | grep -v SERIAL_
hw/char/Kconfig: select SERIAL

hw/char/Kconfig: select SERIAL

Currently, both qemu_devices_reset() and MachineClass::reset() use
ShutdownCause for the reason of the reset. However, the Resettable
interface uses ResetState, so ShutdownCause needs to be translated to
ResetType somewhere. Translating it qemu_devices_reset() makes adding
new reset types harder, as they cannot always be matched to a single
ShutdownCause here, and devices may need to check the ResetType to
determine what to reset and if to reset at all.
This patch moves this translation up in the call stack to
qemu_system_reset() and updates all MachineClass children to use the
ResetType instead.

Per https://discourse.gnome.org/t/port-your-module-from-g-memdup-to-g-memdup2-now/5538
The old API took the size of the memory to duplicate as a guint,
whereas most memory functions take memory sizes as a gsize. This
made it easy to accidentally pass a gsize to g_memdup(). For large
values, that would lead to a silent truncation of the size from 64
to 32 bits, and result in a heap area being returned which is
significantly smaller than what the caller expects. This can likely
be exploited in various modules to cause a heap buffer overflow.
Replace g_memdup() by the safer g_memdup2() wrapper.
Trivially safe because the argument was directly from sizeof.

machine. This will enable us to later support more than 4GB of RAM and is
required that the OS (or PALO bootloader) will start or install a 64-bit kernel
instead of a 32-bit kernel.
Note that SeaBIOS-hppa v16 provides the "-fw_cfg opt/OS64,string=3" option with
which the user can control what the firmware shall report back to the OS:
Support of 32-bit OS, support of a 64-bit OS, or support for both (default).
Wrap firmware loading inside !qtest_enabled() to avoid this warning with
qtest: "qemu-system-hppa: no firmware provided".

Create the device only if there is a corresponding NIC config for it.
Remove the explicit check on nd_table[0].used from hw/hppa/machine.c
which (since commit d8a3220005) tries to do the same thing.
The lasi_82596 support has been disabled since it was first introduced,
since enable_lasi_lan() has always been zero. This allows the user to
enable it by explicitly requesting a NIC model 'lasi_82596' or just
using the alias 'lasi'. Otherwise, it defaults to a PCI NIC as before.

The various operating systems (e.g. Linux, NetBSD) have issues
mapping the power button when it's stored in page zero.
NetBSD even crashes, because it fails to map that page and then
accesses unmapped memory.
Since we now have a consistent memory mapping of PDC in 32-bit
and 64-bit address space (the lower 32-bits of the address are in
sync) the power button can be moved back to PDC space.
This patch fixes the power button on Linux, NetBSD and HP-UX.

Recognize the qemu --nodefaults option, which will disable the
following default devices on hppa:
- lsi53c895a SCSI controller,
- artist graphics card,
- LASI 82596 NIC,
- tulip PCI NIC,
- second serial PCI card,
- USB OHCI controller.
Adding this option is very useful to allow manual testing and
debugging of the other possible devices on the command line.

The physical hardware allows DIMMs of 4 MB size and above, allowing up
to 3840 MB of memory, but is restricted by setup code to 3 GB.
Increase the limit to allow up to the maximum amount of memory.
Btw. the memory area from 0xf000.0000 to 0xffff.ffff is reserved by
the architecture for firmware and I/O memory and can not be used for
standard memory.
An upcoming 64-bit SeaBIOS-hppa firmware will allow more than 3.75GB
on 64-bit HPPA64. In this case the ram_max for the pa20 case will change.
