Now i'm confused. What does rd mean?
I would expect RD mean Reference Design, and that is the complete
device in its box.
Yet, here you have RD for the carrier?
The box itself is called cn9131-ac5x-carrier?
This makes no sense to me.
Maybe i'm understanding this all wrong, and its the carrier which you
are producing a reference design for? The CPU module does not really
matter? I could use any off the shelf ComExpress 7 SOM. The bits you
are trying to sell are on the carrier? But since you are Marvell, you
don't want to recommend using an AMD ComExpress board when you happen
to also have CPU module which would work? But the CPU is not really
the point of this, its the carrier?
