Duplicate Tegra210's copy of this file for Tegra186. This ensures that a /binman node exists in U-Boot's control DT. Subsequent to 3c10dc95bdd0 ("binman: Add a library to access binman entries") this appears to be required. I haven't really investigated why all this is necessary or how it works, but simply observed the boot failure listed below, bisected it, noticed the inconsistency in DT files, and found that fixing it resolved the boot issue.
