I just tested mx6cuboxi with 2019.10-rc4, and it fails to load u-boot.img from MMC:

Works fine with 2019.07.
< xypron> vagrantc: CONFIG_DM_MMC, CONFIG_DM_USB is not used. The board still uses the pre-driver-model drivers. So a candidate to be kicked out of U-Boot.
Happy to test patches; I have several mx6cuboxi supported models available.
live well, vagrant
