You need to make sure the signal names are defined in your part definition.
The format of the intibus command is initbus spimem NCS=<signal name>
SCK=<signal name> MOSI=<signal name> MISO=<signal name>. It looks like you
copied the names of the signals from the example.
Looking at the ar2312 part definition file, it does not appear to have the
pin definitions. You will need to find BSDL file for this part.
