I think you meant that the snowflake board is a carrier board that
uses the "Kontron SL i.MX 8M Mini" SoM, right?

To expand on this, in U-Boot, we are migrating to OF_UPSTREAM, which
means that U-Boot will utilize an upstream version of the device tree.

It is OK to use a temporary dts in U-Boot while the dts is still not in Linux.

When the dts is accepted in Linux, and U-Boot dts repo syncs with
upstream kernel, then the board can migrate to OF_UPSTREAM.

Please submit the imx8mm-mt-snowflake-v2.dts to Linux, wait for some
feedback, and then resend this U-Boot patch with a reference to the
Linux dts submission.

As Tom mentioned, the bootph-* properties are valid upstream, so you
can submit the dts with these nodes and get rid of the -u-boot.dtsi.
