Julien,

Thanks for this contribution!

Could you instead use genimage rather than providing a script to create
the SD card contents ?

You can look at the following examples:

board/cubietech/cubieboard2/genimage.cfg
board/via/imx6_vab820/genimage.cfg
board/intel/galileo/genimage.cfg
board/raspberrypi/genimage-raspberrypi.cfg
board/raspberrypi/genimage-raspberrypi2.cfg
board/orangepi/orangepipc/genimage.cfg
board/wandboard/genimage.cfg

The wandboard one should be particularly useful, since it's also an i.MX6 board.

Why ? Any reason to use EABI over EABIhf, which is now the default in
Buildroot for Cortex-A processors ?

The rest looks good to me. Thanks a lot!
