How to Build Linux-Stable?

another way I am trying to build Linux-stable on board. repository found it on the GitHub page but not sure how to build it. anyone can help me out to build the Linux stable on the CLEARFOG CN9130 PRO device.
steps to build the Linux-stable.


see the following link

you just need to run the runme. sh script and it will build for you the Linux-Stable 5.15


I follow the link and was able to build the script. it builds Linux 5.15 using Base SDK patches and sources files.
now I am trying to build the generic extensions provided by Marvell but have not found any proper way to build for cn9130 on SolidRun documentation.
I have raised a separate query for this on the forum.
please guide me if have any relevant information .
