SATA CD-ROMS are still conventionally used in many
virtual environments, so it's nice to support them
out of the box.
Tested with QEMU 9.2.3 with the following controller
and drive:
qemu-system-loongarch64 -M virt [...] \
-device ahci,id=ahci0,multifunction=on,bus=pcie.0,addr=0x7 \
-drive if=none,id=drive-sata2,media=cdrom,format=raw,aio=threads,file=/path/to/bootable.iso \
-device ide-cd,bus=ahci0.2,drive=drive-sata2,id=sata2,bootindex=102
