I understood what you did, but i am not sure how will it actually work.
I tried to look into kernel source but couldn't find much.

Suppose all three machines/boards are selected and we got one kernel.
Then how should we tell the kernel which machines init routine to be called.
I suppose through uboot only, but not sure how it internally works.

Can you please help me understand that?
