 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
iCore this is not needed?

 Fabio explicitly turns off HDMI. Not needed?

 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?
