[poky] Is there a guide for adding a board to the yocto system?

[Steven Grunza]

I would like to add a board to the yocto system such that instead of
having a line in build/conf/local.conf that reads 

MACHINE ?= "beagleboard"

It would be

MACHINE ?= "my_board_name"


Is there a guide on how to do this?
