Info on holes in Colibri Evaluation Board

I see that Colibri Evaluation Board has some holes to allow proper mounting of Colibri Module.

Two of them are for Colibri Fasteners.

I don’t know what is the purpose of other holes pointed by arrows in the following image

We’ve been desgining our carrier board and I need to know if we shuld have these holes or not.

Thanks in advance.

It’s just a legacy from SO-DIMM standard. You can omit them in your design.
