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
