[PATCH v2] imx: Add support for Ronetix's i.MX7-CM board.

Hi Ilko,

your patch is since a long while in the list. I have merged it a couple
of times but I went back - sorry to not communicate this before.

Your patch create a DCD for the board - but we have full support for
i.MX6 and i.MX to set dinamically the DDR controller in SPL, see
mx7_dram_cfg(), and this makes board/ronetix/imx7-cm/imximage.cfg
superfluous. Do you have evaluated to switch to SPL instead of
hard-coding the DCD into u-boot.imx ?

Best regards,
Stefano Babic
