969ca2f7a1 adb: introduce new ADBDeviceHasData method to ADBDeviceClass
This is required later to allow devices to assert a service request (SRQ)
signal to indicate that it has data to send, without having to consume it.

da52c083ac adb: create autopoll variables directly within ADBBusState
Rather than each ADB implementation requiring its own functions to manage
autopoll state, timers, and autopoll masks prepare to move this information
directly into ADBBusState.

Add external functions within adb.h to allow each ADB implementation to
manage the new autopoll variables.

dcb091c40e pmu: fix duplicate autopoll mask variable
It seems that during the initial work to introduce the via-pmu ADB support a
duplicate autopoll mask variable was accidentally left in place.

Remove the duplicate autopoll_mask variable and switch everything over to
use adb_poll_mask instead.

167f1667b1 adb: fix adb-mouse read length and revert disable-reg3-direct-writes workaround
Commit 84051eb400 "adb: add property to disable direct reg 3 writes" introduced
a workaround for spurious writes to ADB register 3 when MacOS 9 enables
autopoll on the mouse device. Further analysis shows that the problem is that
only a partial request is sent, and since the len parameter is ignored then
stale data from the previous request is used causing the incorrect address
assignment.

Remove the disable-reg3-direct-writes workaround and instead check the length
parameter when the write is attempted, discarding the invalid request.

8d19371593 Stop vhost-user sending uninitialized mmap_offsets
Prior to this change, the vhost_user_fill_msg_region function filled out
all elements of the VhostUserMemoryRegion struct except the mmap_offset.

This function is often called on uninitialized structs, which are then
copied into VHOST_USER_SET_MEM_TABLE and VHOST_USER_ADD/REM_MEM_REG
messages. In some cases, where the mmap_offset was not needed, it was
left uninitialized, causing QEMU to send the backend uninitialized data,
which Coverity flagged as a series of issues.

This change augments the vhost_user_fill_msg_region API, adding a
mmap_offset paramenter, forcing the caller to initialize mmap_offset.

953cd66139 sd/milkymist-memcard: Fix error API violation
The Error ** argument must be NULL, &error_abort, &error_fatal, or a
pointer to a variable containing NULL.  Passing an argument of the
latter kind twice without clearing it in between is wrong: if the
first call sets an error, it no longer points to NULL for the second
call.

milkymist_memcard_realize() is wrong that way: it passes &err to
qdev_prop_set_drive_err() and qdev_realize_and_unref().  Currently
harmless, because the latter uses it only as first argument of
error_propagate().

Making qdev_prop_set_drive_err() fail involves abuse of -global.
Leave handling that to qdev_prop_set_drive(), like we do elsewhere.

9572a78797 qdev: Reject chardev property override
qdev_prop_set_chr() screws up when the property already has a non-null
value: it neglects to release the old value.  Both the old and the new
backend become attached to the same device.  Unlike for block devices
(see previous commit), this can't be observed from the monitor (I
think).

Example: -serial null -chardev null,id=chr0 -global isa-serial.chardev=chr0

Special case: attempting to use the same backend both times crashes:

    $ qemu-system-x86_64 --nodefaults -serial null -global isa-serial.chardev=serial0
    Unexpected error in qemu_chr_fe_init() at /work/armbru/qemu/chardev/char-fe.c:220:
    qemu-system-x86_64: Device 'serial0' is in use
    Aborted (core dumped)

Yet another example: -device with multiple chardev=... (but not
device_add, which silently drops all but the last duplicate property).

Perhaps chardev property override could be made to work.  Perhaps it
should.  I can't afford the time to figure this out now.  What I can
do reject usage that leaves backends in unhealthy states.  For what
it's worth, we've long done the same for netdev properties.

"qdev-properties-system.c: Allow vlan or netdev for -device, not

    $ qemu-system-x86_64 --nodefaults -nic user -netdev user,id=nic0 -global e1000.netdev=nic0

-device and device_add handle the failure:

6172e067a4 fdc: Reject clash between -drive if=floppy and -global isa-fdc
The floppy controller devices desugar their drive properties into
floppy devices (since commit a92bd191a4 "fdc: Move qdev properties to
FloppyDrive", v2.8.0).  This involves some bad magic in
fdctrl_connect_drives(), and exists for backward compatibility.

The functions for boards to create floppy controller devices
fdctrl_init_isa(), fdctrl_init_sysbus(), and sun4m_fdctrl_init()
desugar -drive if=floppy to these floppy controller drive properties.

If you use both -drive if=floppy (or its -fda / -fdb sugar) and
-global isa-fdc for the same floppy device, -global silently loses the
conflict, and both backends involved end up with the floppy device
frontend attached, as demonstrated by iotest 172 (see commit before
previous).  This is wrong.

Desugar -drive if=floppy straight to floppy devices instead, with
helper fdctrl_init_drives().  The conflict now gets rejected cleanly:
first, fdctrl_connect_drives() creates the floppy for the controller's
property, then fdctrl_init_drives() attempts to create the floppy for
-drive if=floppy, but fails because the unit is already in use.

Output of iotest 172 changes in three ways:

1. The clash gets rejected.

2. In one test case, "info qtree" has the floppy devices swapped, and
   "info block" has their QOM paths swapped.  This is because the
   floppy device for -fda now gets created after the one for -global
   isa-fdc.driveB.

3. The error message for -global floppy.drive=floppy0 changes.  Before
   the patch, we set isa-fdc.driveA to -fda's block backend, then
   create the floppy device for it, then move the backend from
   isa-fdc.driveA to floppy.drive.  Floppy creation fails when
   applying -global floppy.drive=floppy0, because floppy0 is still
   attached to isa-fdc.  After the patch, we create the floppy for
   -fda, then set its drive property to floppy0.  Now floppy creation
   succeeds, but setting the drive property fails, because -global
   already set it.  Yes, this is exasperatingly complicated.

2e34818f08 hw/arm/mps2-tz: Use the ARM SBCon two-wire serial bus interface
From 'Application Note AN521', chapter 4.7:

  The SMM implements four SBCon serial modules:

  One SBCon module for use by the Color LCD touch interface.
  One SBCon module to configure the audio controller.
  Two general purpose SBCon modules, that connect to the
  Expansion headers J7 and J8, are intended for use with the
  V2C-Shield1 which provide an I2C interface on the headers.
