In U-Boot now the update to driver model and device tree is now ongoing.

Actually I have tried to enable dm_mmc by including select DM select DM_MMC select OF_CONTROL imply CMD_DM into kconfig. Unfortunately, this breaks everything. I don’t even get any output on my console. u-boot breaks at in bootstage_error (id=BOOTSTAGE_ID_NEED_RESET) at include/bootstage.h:381 Do you have any links, where I can find further information about how to implement device model? I have looked into your provided links. Unfortunately i don't see big differences at the moment. I would really like to get the code up to date and in line with the latest requirements 😊 Thanks for your support.

In U-Boot now the update to driver model and device tree is now ongoing. You may want look for some already converted i.MX6 boards as a reference (they are not yet in the mainline, but shall be): http://patchwork.ozlabs.org/cover/1112747/ http://patchwork.ozlabs.org/cover/1102875/ or this series: https://patchwork.ozlabs.org/patch/1095619/ > > Sorry for the inconvenience.
