Also, Robert pointed out I missed K3_PM_SYSTEM_SUSPEND=1 :(

I am wondering how to let people read a single page and know all the
steps to build the components needed instead of referring to other docs.

Are you thinking something like:
https://gist.github.com/nmenon/8c883ebf37a5d6021400cce9d76bfc35

I am not a sphinx expert, is this something you'd not like?

I have had feedback from multiple folks saying one single doc showing
all the build commands for the platform is what they are trying to get..
so this might be a good trade-off, perhaps?

I really did think of it, but then, if we did have config fragments, I
could have reused things, but at the moment, it is a different
defconfig.. hence, though it is same at the moment, I cant guarantee it.
