5824fad4e9 hw/boards: Do not create unusable default if=sd drives
A number of machines create an if=sd drive by default even though
they lack an SD bus, and therefore cannot use the drive.

This drive is created when the machine sets flag
@auto_create_sdcard.

See for example running HMP "info block" on the HPPA C3700 machine:

  $ qemu-system-hppa -M C3700 -monitor stdio -S
  (qemu) info block

  floppy0: [not inserted]
      Removable device: not locked, tray closed

  sd0: [not inserted]
      Removable device: not locked, tray closed

  $ qemu-system-hppa -M C3700 -sd /bin/sh
  qemu-system-hppa: -sd /bin/sh: machine type does not support if=sd,bus=0,unit=0

Delete that from machines that lack an SD bus.

Note, only the ARM and RISCV targets use such feature:

 $ git grep -wl IF_SD hw | cut -d/ -f-2 | sort -u
 hw/arm
 hw/riscv
 $

cdc8d7cada hw/boards: Rename no_sdcard -> auto_create_sdcard
Invert the 'no_sdcard' logic, renaming it as the more explicit
"auto_create_sdcard". Machines are supposed to create a SD Card
drive when this flag is set. In many cases it doesn't make much
sense (as boards don't expose SD Card host controller), but this
is patch only aims to expose that nonsense; so no logical change
intended (mechanical patch using gsed).

Most of the changes are:

  -    mc->no_sdcard = ON_OFF_AUTO_OFF;
  +    mc->auto_create_sdcard = true;

Except in
 . hw/core/null-machine.c
 . hw/arm/xilinx_zynq.c
 . hw/s390x/s390-virtio-ccw.c
where the disabled option is manually removed (since default):

  -    mc->no_sdcard = ON_OFF_AUTO_ON;
  +    mc->auto_create_sdcard = false;
  -    mc->auto_create_sdcard = false;

and in system/vl.c we change the 'default_sdcard' type to boolean.

c36ec3a965 hw/microblaze/s3adsp1800: Explicit CPU endianness
By default the machine's CPU endianness is 'big' order
('little-endian' property set to %false).

This corresponds to the default when this machine was added;
see commits 6a8b1ae202 "microblaze: Add petalogix s3a1800dsp
MMU linux ref-design." and 72b675caac "microblaze: Hook into
the build-system." which added:

  [ "$target_cpu" = "microblaze" ] && target_bigendian=yes

Later commit 877fdc12b1 ("microblaze: Allow targeting
little-endian mb") added little-endian support, forgetting
to set the CPU endianness to little-endian. Not an issue
since this property was never used, but we will use it soon,
so explicit the endianness to get the expected behavior.

181b3a7bb0 hw/microblaze: Deprecate big-endian petalogix-ml605 & xlnx-zynqmp-pmu
The petalogix-ml605 machine was explicitly added as little-endian only
machine in commit 00914b7d97 ("microblaze: Add PetaLogix ml605 MMU
little-endian ref design"). Mark the big-endian version as deprecated.

When the xlnx-zynqmp-pmu machine's CPU was added in commit 133d23b3ad
("xlnx-zynqmp-pmu: Add the CPU and memory"), its 'endianness' property
was set to %true, thus wired in little endianness.

Both machine are included in the big-endian system binary, while their
CPU is working in little-endian. Unlikely to work as it. Deprecate now
as broken config so we can remove soon.

7e6b5497ea hw/char: Extract serial-mm
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
  hw/char/Kconfig:    select SERIAL
  hw/char/Kconfig:    select SERIAL
  hw/char/Kconfig:    select SERIAL

  # grep -r -e "/serial\\.h"
  include/hw/char/serial-mm.h:#include "hw/char/serial.h"
  hw/char/serial-pci-multi.c:#include "hw/char/serial.h"
  hw/char/serial.c:#include "hw/char/serial.h"
  hw/char/serial-isa.c:#include "hw/char/serial.h"

0de89a8632 hw/microblaze: Replace drive_get_next() by drive_get()
drive_get_next() is basically a bad idea.  It returns the "next" block
backend of a certain interface type.  "Next" means bus=0,unit=N, where
subsequent calls count N up from zero, per interface type.

This lets you define unit numbers implicitly by execution order.  If the
order changes, or new calls appear "in the middle", unit numbers change.
ABI break.  Hard to spot in review.

Machine "petalogix-ml605" connects backends with drive_get_next() in a
counting loop.  Change it to use drive_get() directly.  This makes the
unit numbers explicit in the code.

e178113ff6 hw: Replace anti-social QOM type names
Several QOM type names contain ',':

    ARM,bitband-memory
    etraxfs,pic
    etraxfs,serial
    etraxfs,timer
    fsl,imx25
    fsl,imx31
    fsl,imx6
    fsl,imx6ul
    fsl,imx7
    grlib,ahbpnp
    grlib,apbpnp
    grlib,apbuart
    grlib,gptimer
    grlib,irqmp
    qemu,register
    SUNW,bpp
    SUNW,CS4231
    SUNW,DBRI
    SUNW,DBRI.prom
    SUNW,fdtwo
    SUNW,sx
    SUNW,tcx
    xilinx,zynq_slcr
    xlnx,zynqmp
    xlnx,zynqmp-pmu-soc
    xlnx,zynq-xadc

These are all device types.  They can't be plugged with -device /
device_add, except for xlnx,zynqmp-pmu-soc, and I doubt that one
actually works.

They *can* be used with -device / device_add to request help.
Usability is poor, though: you have to double the comma, like this:

    $ qemu-system-x86_64 -device SUNW,,fdtwo,help

Trap for the unwary.  The fact that this was broken in
device-introspect-test for more than six years until commit e27bd49876
fixed it demonstrates that "the unwary" includes seasoned developers.

One QOM type name contains ' ': "ICH9 SMB".  Because having to
remember just one way to quote would be too easy.

Rename the "SUNW,FOO types to "sun-FOO".  Summarily replace ',' and '
' by '-' in the other type names.

617160c9e1 load_elf: Remove unused address variables from callers
Several callers of load_elf() pass pointers for lowaddr and highaddr
parameters which are then not used for anything. This may stem from a
misunderstanding that load_elf need a value here but in fact it can
take NULL to ignore these values. Remove such unused variables and
pass NULL instead from callers that don't need these.

Not exactly elegant, I'm afraid.

The "when != lbl:" is necessary to avoid transforming

         if (fun(args, &err)) {
             goto out
         }
         ...
     out:
         error_propagate(errp, err);

even though other paths to label out still need the error_propagate().
For an actual example, see sclp_realize().

Without the "when strict", Coccinelle transforms vfio_msix_setup(),
incorrectly.  I don't know what exactly "when strict" does, only that
it helps here.

The match of return is narrower than what I want, but I can't figure
out how to express "return where the operand doesn't use @err".  For
an example where it's too narrow, see vfio_intx_enable().

Silently fails to convert hw/arm/armsse.c, because Coccinelle gets
confused by ARMSSE being used both as typedef and function-like macro
there.  Converted manually.

Line breaks tidied up manually.  One nested declaration of @local_err
deleted manually.  Preexisting unwanted blank line dropped in
hw/riscv/sifive_e.c.

db873cc5d1 sysbus: Convert qdev_set_parent_bus() use with Coccinelle, part 2
This is the same transformation as in the previous commit, except
sysbus_init_child_obj() and realize are too separated for the commit's
Coccinelle script to handle, typically because sysbus_init_child_obj()
is in a device's instance_init() method, and the matching realize is
in its realize() method.

Perhaps a Coccinelle wizard could make it transform that pattern, but
I'm just a bungler, and the best I can do is transforming the two
separate parts separately:
