True. The alternative is to hardcode the knowledge of the spec in the management layers (since you cannot do index=0|1, you have to do something akin to iobase=0x3f8 for the x86 COM1 port). I guess you will still need two sysbuses so that you get the correct hierarchy in the device tree, right? And we're back to the beginning of the discussion: the distinction between a "sysbus" and a "platform bus" disappears, and in fact it even feels more accurate to just call these things "sysbuses"...
