Deleting the &binman node from the venice-u-boot.dtsi file appears to make the problem go away, and binman is still making the image.

Adam,

I don't quite follow. I don't see any binman nodes in
arch/arm/dts/imx8mm-u-boot.dtsi.

I know that Marcel submitted a patch that added them (and I'm not sure
if he added them yet in a way that was compatible with multiple fdt's)
but this hasn't been merged yet so I don't see any duplicate binman
nodes for venice.
