I’m running the NXP i.MX6Q SDB using U-Boot Falcon mode to reduce booting time. I currently managed to boot a complete Linux image up to the login prompt in about 0.9 second.

To upload the image into the SD card, use the following command:
$ sudo dd if=falconmode_imx6qsabresd.sdcard of=/dev/sdX ; sync
The tutorial for enabling Falcon mode is available here.
