If you're cc'ed, you added a section to docs/system/deprecated.rst that
is old enough to permit removal. This is *not* a demand to remove, it's
a polite request to consider whether the time for removal has come.
Extra points for telling us in a reply. "We should remove, but I can't
do it myself right now" is a valid answer. Let's review the file:

Kővágó, Zoltán:
``QEMU_AUDIO_`` environment variables and ``-audio-help`` (since 4.0)
'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
The ``-audiodev`` argument is now the preferred way to specify audio
backend settings instead of environment variables. To ease migration to
the new format, the ``-audiodev-help`` option can be used to convert
the current values of the environment variables to ``-audiodev`` options.
Kővágó, Zoltán:
Creating sound card devices and vnc without ``audiodev=`` property (since
4.2)
''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
When not using the deprecated legacy audio config, each sound card
should specify an ``audiodev=`` property. Additionally, when using
vnc, you should specify an ``audiodev=`` property if you plan to
transmit audio through the VNC protocol.

Creating sound card devices using ``-soundhw`` (since 5.1)
''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
Sound card devices should be created using ``-device`` instead. The
names are the same for most devices. The exceptions are ``hda`` which
needs two devices (``-device intel-hda -device hda-duplex``) and
``pcspk`` which can be activated using ``-machine
pcspk-audiodev=<name>``.

RISC-V ``-bios`` (since 5.1)
''''''''''''''''''''''''''''
QEMU 4.1 introduced support for the -bios option in QEMU for RISC-V for the
RISC-V virt machine and sifive_u machine. QEMU 4.1 had no changes to the
default behaviour to avoid breakages.
QEMU 5.1 changes the default behaviour from ``-bios none`` to ``-bios
default``.
QEMU 5.1 has three options:
1. ``-bios default`` - This is the current default behavior if no -bios
option
is included. This option will load the default OpenSBI firmware
automatically.
The firmware is included with the QEMU release and no user
interaction is
required. All a user needs to do is specify the kernel they want to
boot
with the -kernel option
2. ``-bios none`` - QEMU will not automatically load any firmware. It is
up
to the user to load all the images they need.
3. ``-bios <file>`` - Tells QEMU to load the specified file as the
firmwrae.
This has already been acted upon in the code, we now default to
including a "bios" with RISC-V softmmu which is what this is
describing.
Do we need to take any action to indicate that it's already in effect?
