To make it easier to sync dts files with Linux add specific tweaks for U-Boot in separate files, specifically allowing SPL to make use of MMC.

It seems you missed to add CONFIG_OF_CONTROL=y and CONFIG_DM_MMC=y in the defconfig so that Cubox could be really converted to DM.

Thanks for your comments. My intention was to initially send the device tree patches and in a different patchset update the configuration, as it requires to run different tests (i.e. boot from SATA). Also I felt that this patch has meaning by itself, as it could be useful for people willing to test DM on this board.
Please let me know you think my approach is not the correct one.
Regards,

It is preferred that you resend the dts pieces only when the cubox board is really converted to DM, otherwise you are only adding "dead code".
Also the imx6dl-cubox-i-u-boot.dtb does not need to be explicitly added in the Makefile.
It gets built automatically by the core U-Boot Makefile logic.
Thanks

Thanks for the suggestion. I will wait for some SATA tests before re sending these patches.

Thanks for the information. I was confused by entries like "r8a7790-lager-u-boot.dtb" in the Makefile but you are right. I will take this into account for v2.
Thanks
