Character devices defined with -serial and -parallel are for board initialization to wire up. Board code examines serial_hds[] and parallel_hds[] to find them, and creates devices with their qdev chardev properties set accordingly. Except a few devices go on a fishing expedition for a suitable backend instead of exposing a chardev property for board code to set: they use serial_hds[] (often via qemu_char_get_next_serial()) or parallel_hds[] in their realize() or init() method to connect to a backend. Picking up backends that way works when the devices are created by board code. But it's inappropriate for -device or device_add. Not only is it inconsistent with how the other characrer device models work (they connect to a backend explicitly identified by a "chardev" property), it breaks when the backend has been picked up by the board or a previous -device / device_add already. Example: $ qemu-system-ppc64 -M bamboo -S -device i82378 -device pc87312 -device pc87312 qemu-system-ppc64: -device pc87312: Property 'isa-parallel.chardev' can't take value 'parallel0', it's in use Mark them with suitable FIXME comments.
