Para dar soporte a una nueva board basada en imx en el kernel es necesario tener un fichero de configuracion defconfig (.config) y una dtb.
Por defecto empezaremos con un defconfig ya creado por igep para procesadores imx

Para que el kernel compile la dtb es necesario tener una dts con la configuración de los periféricos y los drivers que los gestionan,ademas de una anidación al dtsi del procesador correspondiente ( en este caso imx6 ya sea quad, dual, solo ...)

Las DTS están anidadas, esto quiere decir que se cogerá la dtb generada a partir de la .dts dependiendo del procesador que monte igep en este caso.
Para que el kernel compile las .dts en dtb se ha de añadir en el Makefile de arch/arm/boot/dts/

3- Ejecutar el menuconfig para optimizar la configuracion a traves del menú.

Guardar la configuracion del menuconfig en .config
4- Compilar la imagen los modulos y las dtb

</div>
</div>
|}</div>
</div>
</div>
5- Instalar en el rootfs los modulos del kernel que son cargables ( es decir que no estan built-in)
