But, I didn't get how to integrate with existing message queue. Memory
mapped read by-passes message queue of SPI core. Could you please
explain a bit more on integrating with message queue? Did you mean
locking the existing message queue when memory mapped read is being
requested?

Yes, and also making sure that we don't everything gets processed in
order so memory mapped requests come after any commands needed to set
them up and don't starve other work.

Ok, thanks for the clarification!
