At present u-boot.bin has a very standard meaning - it is U-Boot with the DT.

Boards which need something more than that can/should use binman to
create a separate file.

I certainly agree that u-boot-with-dtb.bin is a terrible name, though.
Something more descriptive would be better.

But is it possible to drop these SoC-specific rules in the Makefile
and just build everything needed in the standard binman rule in the
Makefile?

Simon
