Yes, Octeontx needed mbox definitions and it was defined at event area.

But You are right that adding event dependency in mempool may create issues
for future feature like you mentioned.

> Ideally, if you have common code, you should put that in bus or mempool . This way you can make event, net or sec etc dependent on bus or mempool  and not the otherway around.

Right.
Proposed change for makefile will be:

diff --git a/drivers/Makefile b/drivers/Makefile
index 3a5b22342..0467250aa 100644
--- a/drivers/Makefile
+++ b/drivers/Makefile

 DEPDIRS-crypto := bus mempool

Can you give it a try and let me know your feedback.

Thanks.
