Do we have some sane way to have user-pluggable sysbus devices on arm?
I've played around with that a bit, with the uefi variable service I'm
working on. Specifically I'd prefer to *not* have a patch wiring things
up in machine type code like this ...
20250107153353.1144978-20-kraxel@redhat.com/">https://lore.kernel.org/qemu-devel/20250107153353.1144978-20-kraxel@redhat.com/
... and just use 'qemu -device uefi-vars-sysbus' instead.
Something like AcpiDevAmlIfClass but for device tree seems to not exist
though. Also apparently AcpiDevAmlIfClass is not used.
take care,
Gerd
