So that bootargs would not have to be modified when filesystem is on eMMC.
I don't know if we can, but even if we could, we take care of the same bootargs working on two boards (say sdp and panda) *if* on sdp I have my filesystem on eMMC and on panda I have it on external card. What happens if I want to use my filesystem on both boards on external card?
