Teresa,

I've noticed many of the imx8m boards migrating to using binman for
image packaging.

Doesn't this change from having a single flash.bin encompasing the SPL
and U-Boot proper to having split files? I noticed that happened with
imx8mm_evk for example when it switched to binman.

What are the benefits to using binman?

Thanks,

Tim
