setenv("soctype", cputype);So you have soc=mx6 and soctype=<value of cputype>, if CONFIG_SYS_SOC is set.
Is it important to have both or you can simply redefine the variable "soc" ?

Hi Stefano,
Yes, I do feel its important, although the name and where its set is debatable.
There are enough similarities between an IMX6DUAL/IMX6QUAD vs an IMX6SOLO/IMX6DUALLITE making it such that if your board supports all 4 CPU's, you would usually have just two device-tree files: imx6q-<foo>.dtb (supporting both the QUAD and the DUAL soc variants) and imx6dl-<foo>.dtb (supporting both the DUALLITE and SOLO soc variants).
Regards,
Tim
