Sorry that I didn't see this during the review of your patch that made this change. If u-boot-fw-utils-cross of intended to be used on the host, why did you then replace the old u-boot-fw-utils with this recipe? 

The old u-boot-fw-utils were to create fw_printenv to be used on the _target_ not on the host. Unfortunately, I don't think this was ever mentioned during the patch review...

Yep, so the commit log that makes the transition from u-boot-fw-utils to u-boot-fw-utils-cross should have mentioned that the purpose of those two packages are completely different.

I've got a working u-boot-fw-utils recipe that I can submit. I'll look into this on Monday morning, to ensure that it's of enough quality to publish. 

Just curious, what use case do you have for fw_* the build host?
