This is the same as board/freescale/imx6-sabresd/linux_qt5.fragment, perhaps
that file could be used directly?

Fabio (in Cc) changed this to card0 with the bump to Linux 4.13.3. For the

Fabio converted the imx6-sabresd to SPL boot, so that the same defconfig can be
used for different boards. Could the enigcam boards use the same defconfig?
