Nevertheless, as long as nobody has a hint where to find that
ppc405_rom.bin, I think both boards are pretty useless in QEMU (as

possible
to use a Linux image with the "-kernel" CLI option directly).
It is at least in theory possible to run bare-metal code on
either board, by passing either a pflash or a bios argument.
True. I did some more research, and seems like there was once support
for those boards in u-boot, but it got removed there a couple of years
ago already:
https://gitlab.com/qemu-project/u-boot/-/commit/98f705c9cefdf
https://gitlab.com/qemu-project/u-boot/-/commit/b147ff2f37d5b
https://gitlab.com/qemu-project/u-boot/-/commit/7514037bcdc37
But I agree that there seem to be no signs of anybody actually
successfully using these boards for anything, so we should
deprecate-and-delete them.
Yes, let's mark them as deprecated now ... if someone still uses them
and speaks up, we can still revert the deprecation again.
I really would like to be able to use them to validate Linux Kernel
changes, hence looking for that missing BIOS.
If we remove ppc405 from QEMU, we won't be able to do any regression
tests of Linux Kernel on those processors.
