Hello Alexander,

Have you tried to configure the build to use upstream DTS ? this should
be available in the U-boot dir. CONFIG_OF_UPSTREAM I believe.

Also, if you really want to update this u-boot DT, you would have to
copy it as-is, no stripping. Even if the props are unused. The only real
issue would be if Uboot stops working or gets confused by these extra props
