Generic extension supported for SolidRun?

Hello,

as cn9130 Build script gives us a way to build using Base SDK’s patches files and source files.
resource link for cn9130 Build script is as below,
https://solidrun.atlassian.net/wiki/spaces/developer/pages/201097229/CN913x+Build+-+Script

so my question is can we build generic extensions provided by Marvell for cn9130. I have referred to the site but have not found any relative information regarding generic extensions.

Thanks.
