Yes. As Thomas says, if your device is using serial_hds[] directly it is not user creatable. The ideal design here is that the device does not touch serial_hds[] at all, but instead has qdev properties for char devices, which the board model code wires up based on serial_hds[]. (In this case you could make them just be alias properties into the escc object that the macio device creates.) Either way I don't think there's any reason for the device to be user-creatable. thanks -- PMM
