Well, the only prerequisite is the image created properly, with holes.
The partition does not matter then.

Bmap-tools was added to wic in Yocto, AFAIK, but I never used
wic/yocto. May be one of the folks in CC knows?

I do not know dfu-util either, so I di not know for sure what it takes
to make it use bmat-tools. I guess you or someone should just try and
see.
