I also agree with Kenneth opinion. It would be good to use we're going to
use actually. However, in our case, I don't much mind to use SBS in WK1 DRT
because WK2 is target to ship.
Beside we need to support pixel-test, so I don't mind to use SBS in WK1 to
support pixel-test. When pixel-test is stable on EFL port, then, probably
we can consider it on TBS.
