U-Boot (the Universal Boot Loader) v2020.10 is out. “With this release
we have a number of “please migrate to DM” warnings that are now 1 year
past their warning date, and well past 1 year of those warnings being
printed. It’s getting up there on my TODO list to see if removing
features or boards in these cases is easier.“
