[coreboot] how to use TianoCore as a coreboot payload

[WANG Siyuan]

In this page http://www.coreboot.org/TianoCore , It is said that TianoCore
could be a payload of coreboot to implement opensource UEFI environment.
Now, I have built UDK(UEFI development Kit) successfully.
Then what to do next? how to use these as payload of coreboot?
