* Method for initializing the context with the SPIs. The reason why we do this is due to the fact that
* when custom SPI implementations are done and users don't set {@code proc:none} then our processor
* would be triggered. And this context will always get initialized and the SPI won't be found. However,
* if this is lazily evaluated it won't be a problem, as in the SPI implementation module there won't be any
* processing done.
