I can guarantee that there are no deployed U300, Nomadik or Ux500 systems out there with DTBs deployed in them, and for certain no products. At one point that was the criterion... All setups actually use the appended device tree. In worst case I guess mmc-cap-sd-highspeed and mmc-cap-mmc-highspeed could be put as aliases into the generic parser?
